Oh and then again, it's a dark one but in a good way as well Good work with the background and the model. I just have a little, very little suggestion: Do make expression of the main object (model) come out with a bit more clear details. Guess it gone a little blur to recognize her face. But apart from that, it's a great job overall!
hmm interesting shop, I like the strong central figure on that background image. I might suggest trying different lighting on her though, currently she has a quite strong light on her face from above whereas the background has a softer light behind her~
