You know, fantasy isn't my game, but I'll give it a try. The reason I didn't reply at the first time was because I felt that I didn't knew enough about the story. So dropping in to do edits would just made me to look more idiotic than what I am. This chapter needs the other bits and I'm still feeling that it cannot be judged completely without that knowledge. So here's my shot in the darkness. Ignore it, if you will.
The breeze trickled through the canopy of lemon trees, casting its refreshing touch throughout the orchard. Emylynn smiled, and pulled the hair back from her head, determined to enjoy every second of this blessed coolness.
What a day.What a lovely day.And if only she didn’t have her shadow, then the day would be perfect.
As you can see I added a few words and removed some as I felt they were too wordy for the character. I think you are trying your best to make her feel happiness at the beginning. But what I couldn't understand is the last sentence with the reference to the shadow as the "shadow" can imply to so many things.
Emylynn was sure the gods gave the world younger sisters to torture their siblings, and so far Alyce had been doing a more than satisfactory job. And she thought: Oh Lord could you not take her away?
‘When do you think Ben’s going to ask me to the dance?’ Alyce asked her, for what must have been the hundredth time, which was ninety-nine times more than Emylynn felt like answering.
If you meant that the shadow in the last reference is her sister's shadow, then I think you could clarify it a bit. In here, especially in the second para, I feel you could had done the dialogue and narrative thought the other way around, and continue the narrative flow with the dialogue and response.
Also bless for Alyce for thinking men. To me that makes her three dimensional and not the brat Emylynn sees her being.
A flurry of possible answers raced through her head, each one worse than the next, and no less true than the first. She bit her tongue. Emylynn couldn’t be sure their father’s stable hand had even looked Alyce’s way, let alone wanted to ask her to the spring dance. But Alyce wasn't bothered about hearing an answer to first as she already popped the next question: ‘What should I wear?’
I like your stoic way of staying in her head and not forcing her to converse. And if you do the prose this way then the next para is even more funnier than what I was at the beginning.
Try feathers, or maybe a blue gown with an apron? How about pink tutu with oversized white ribbons? Emylynn knew better than to say any of that out loud; Alyce was famous for her tantrums. She’d been dealing with them for ten years now, ever since Alyce had turned four and learnt how to wrap their father around her little finger.
What I highlighted with poisonous green is something you should consider removing, as to me it takes more away than what it adds. Maybe some would say it's an infodump, but you know better, as the readers might or might not get that info from reading between the lines in case you decide to continue straight away with the dialogue line.
It's a suggestion and it'll certainly will speed up the pace.
‘Maybe I could wear Mother’s dress?’
Emylynn groaned. That thing. They’d had this conversation before. So many times. And she knew what was coming, and knew better than to answer.
She busied herself by plucking a lemon from the nearest tree and placing it in the basket that cheerfully motored along by her side, the casual swishing of its propellers keeping the contraption afloat.
Emylynn passed underneath a low hanging branch and proceeded to the next tree, but Alyce’s hand tugging on her sleeve brought Emylynn up short. She glanced down at it, then up at Alyce’s pleading face and she sighed. ‘I don’t think you’ll fit in it.’
Why don’t you ever listen to me? You’re too fat.
I think the last personal thought is too much. The implication is there, in her reply. And if you remove the mother reference, it'll become even more personal.
The reason why add the few word at the beginning is to bring the character POV much closer than what you had in there previously. And it just enhances her stoicism.
Alyce’s face darkened and she started to tremble as storm clouds brewed in her eyes. ‘Oh, and I suppose the dress will fit you, won’t it?’
The red highlight shows you the fat over the meat. It's over description and I feel that is should go as it doesn't really add much. The dialogue is more important.
Another lemon went in the basket. Emylynn avoided making eye contact with her sister; that would be fatal. She wouldn’t be able to hide the annoyed scowl on her face. ‘I’ll help you make a nice dress to wear.’
This para feels weak. I'm marked with poison green the bit I'm not so sure.
‘I don’t want to make one, I want Mother’s dress!’Emylynn sighed deeply. What there was that she could say?
And I’d like to be left alone. We don’t always get what we want.
'What are you huffin' and puffin'?'
I really didn't like the personalised thought was as strongly associated to the dialogue line as it could had been. Hence the narrative replacement. Also I thought the most annoying dialogue in the history of world line would drive her mental state better than the personalized thought.
Emylynn breathed deeply, to control her frustration, then tore another lemon from a branch and chucked it at the basket, which leaped forward to catch it when the lemon fell short of its rim.
The beginning of this para doesn't associate as well with the end of the last as it could especially as I understand that she's really annoyed. I'd like her ribbing the lemon off the branch rather than trying to calm her nerves as it'd show more of her stoic anger than the previous description.
‘Don’t you have jobs to do?’ Emylynn asked.
‘Matt’s doing them,’ Alyce answered, and followed along, evidently missing the hint, or deliberately ignoring it. Knowing Alyce it was likely the latter.
‘You need to stop encouraging him.’
‘Why?’
Emylynn sighed. ‘Because it’s cruel.’ Because you’re a spoiled brat that should learn to do something for herself!
I feel you should remove the dialogue line and just drop in the thought.
‘He doesn’t seem to mind.’
Emylynn turned, placed her hands on her hips and said, ‘One day he will grow a brain and realise he’s barking up the wrong tree.’
Alyce grinned. ‘As long as it’s not any time soon, cos I’ve still got the chickens to feed.’
‘You know Brandt doesn’t like you taking advantage of him like that.’
‘But Uncle Brandt isn’t here right now.’ Alyce waved her hand around victoriously. 'Is he?'
‘That’s not the point.’
‘Then what is?’
Emylynn groaned, and tugged on another lemon, it held on to its branch. She glared at it and pulled harder. The lemon came loose and the branch quickly flicked back up into the depths of the tree.
‘You ...’ Alyce laughed as the tree spattered loose leaves over Emylynn. 'You look like...'
Nice, nice dialogue. The edit at the end is to enhance the drama. If you would leave Emylynn's line in its original place, it would ruin your carefully build up tension between the characters.
Emylynn shook off the leaves and glared at her. ‘And you look like Mistress Mertellie’s crock-pot.’ Emylynn quickly hid her smile.
Alyce’s mouth fell open. ‘Did you just call me fat?’
F***ing yeah I did. ‘I take it you don’t look in the mirror much?’
When you use thoughts associated dialogue lines, always do it short thought first and then drop in the controverting dialogue line. Remove my thought as the language isn't from this world.
Alyce’s face returned to a deep shade of red, and her hands balled into fists. She glared furiously at Emylynn. Suddenly she turned away, storming across the orchard, shoving aside a branch that got in her way. She stopped at the edge of the orchard, and turned back towards Emylynn.
‘I hate you!’ she said, turned away again, and was soon lost from sight.
Emylynn watched her go, thinking she should follow after, knowing she’d gone too far this time. Emylynn knew if she didn’t stop Alyce now, there’d be a series of doors slamming shut in the girl’s wake, a frown from their father, and then he’d be telling her to go calm Alyce down, again!
It would be so much easier if she just learnt how to grow up! She sighed, and ran after. The basket raced to keep up with her, its engine revving madly. It made a loud screeching sound and suddenly there were lemons on runaway courses in all directions.
Emylynn stopped, and looked back at it. The propeller had caught on the raised root of a tree and turned the basket upside down, before the mechanism had seized and it tumbled to the ground.
Her face gradually slid into a look of resignation. Sometimes I hate my life. A door slammed shut in the distance. Make that all the time.
Sorry.
