Or good news.
Starlights, at 30,000 words each, what you have written are two novellas, which would be tremendously hard to place with any publisher, as book publishers almost always want novels and magazines almost always want short stories (though they will go for novelettes from established writers).
So my first bit of advice to you would be to expand what you have ... expand it a lot. Are these YA novels (that is, do they fall into the so-called young adult category for readers in their early to mid-teens) or are they meant for adult readers? If YA you will need around 70,000 words, although some go much longer. If meant for older readers, and you are writing fantasy, you'll probably need at least 100,000 words.
Are these books directly related, or do you have two entirely separate stories? If you have a story and its sequel, you may be able to combine them into one book, and that will partly address the problem of length.
Otherwise, when you have been here long enough and have made the necessary contribution to the site, then you might indeed want to put up a short sample of your writing for critique and perhaps get some advice, not only on improving your writing in general, but on where and how you might expand in a way that will enhance what you have.
J Riff, it's nice of you to encourage new members to join in, but you do know that we have rules in the Critiques section about posting around the site for a while before "slinging" up work for critiques, don't you? Or do you? Maybe you should drop by and read the rules if you don't, because it would be a pity if a brand new member followed your advice, only to be disappointed when their thread was locked.
