I guess you've not seen my earlier post yet. I'll pull the October piece for you, in case you don't get round to it before the time for editing elapses.
August: I had a several nit-picky issues with this piece, and three or four major problems. Nit-picks first:
“$689.” he said, -- punctuation wrong -- should be “$689,” he said.
“No problem. What a world we live in.” I marveled. -- this is probably also wrong punctuation, as I imagine you mean the "marveled" to act as a speech tag. If so, again a comma after "in" not a full stop. But other people might mark you down for using a non-standard tag (he said, gasped, croaked etc are all fine, but he smiled or smirked and non-verbal tags get people annoyed hereabouts...)
Its tan-gold skin quivered; it moaned and reached out to me. -- in two minds about that semi-colon.
widely tense -- I think I get what you're aiming for, but it didn't work for me, not least as I couldn't see why she would be tense (I couldn't work out if she were sentient)
caught the electro-carbon walls glow. -- missing apostrophe -- wall's or walls' depending on how many are glowing
I salivated for it: a lonely hypothalamus, a genuine need, warm flesh and a functional torso. -- I don't know if you intended this to sound creepy, as it really did to me, but more importantly I couldn't understand the lonely hypothalamus bit.
These things might sound petty, but when the field is so strong, any error is enough to winnow out a story. I have voted for pieces which have errors of this kind, but the writing has to be tip-top or the story incredible for me to do that. So I think it is a case of checking thoroughly before posting, and if you're not sure of punctuation, look it up.
Anyway, the bigger matters. As a purely personal issue, the feminist in me revolted at the concept and at the narrator's use of "it" not "she" so the piece was fighting uphill against my prejudices.
More importantly, there wasn't enough of an actual story there for me -- ie nothing happens except the narrator buys what I assume is a sex toy. I need to see some movement in a piece, some consequence. Also, for me there was no change shown, as required by the theme -- if you'd made it clear he'd taken an entertainment centre in for upgrade, that would have been a different matter, but I couldn't see that here. The last line, too, I didn't think added anything to what had been said, so giving extra stress to it with its own paragraph and the ellipsis seemed a mistake.
September: again a couple of minor nit-picks, but two or three larger issues.
In 1904 CE people first heard the quartz radio. -- I'd have put a comma after 1904, especially as you have one after 5000 BCE.
In 5000 BCE, there in the mountain Abraham stretched forth his hand, and took the knife to slay his son. -- I'd have comma'd after mountain, but not after hand
Those wouldn't have affected my marking, as I can see they're optional commas, but
to his assistant, “But our -- would have resulted in a lower mark. Either full stop after assistant, or a lower case "b" for "but".
The real problem I had, though, is that the final para didn't make sense to me and had nothing to do with the rest of it. We've no idea who this Grathyx is or what he's doing there -- clearly listening, but why? I also didn't understand what he said -- it sounded very good, but in terms of actual meaning it left me behind. To me, you needed to integrate this guy with the Abraham story better, or at least make it clear what was going on. And again, to me it wasn't enough of a story as a whole, with a beginning, middle and end.
In addition, I couldn't actually see where the alternative history was, save perhaps in the use of the radio before its original invention, but that didn't change history, just gave an apparent explanation for the angel of the lord stopping him, which to me isn't the same thing. For me, you would have needed to show something different arising from true history, and something that has consequences, dire or otherwise.
Hope some of that helps.
