I think she looks great and the piece is really nice to look at overall. Her eyes are red, though. Anyway, it's a really nice piece and I love the general feel it has; her style and attitude are both there so it looks fantastic.
Sorry to hear about your artist's block; that always sucks a lot. Here's hoping you find inspiration again soon!
Sorry you have an artblock. That always sucks. I'm sure it will go away VERY soon! I think you did so great on this! I don't think you need to remake it! She's gorgeous and i love the background. And her necklace! ^^
