Comes off a little soft and grainy to me, I'm afraid. Not sure what to suggest, though. Could be a lighting thing, could be an overall sharpness thing. Could be the result of a severe crop, perhaps?
I like the abstract idea on this shot but i don't like the harsh reflections of light at the glass and i thing it's a little OOF. I like the colors too, maybe you could have explored it better. Good idea, sorry if i was rude, good luck!
