this is an interesting photo, I think it may have more of an impact with either the model more in focus or another light source lighting the model equal to the dress.
I like the idea itself but I think you could have executed it better, what bothers me most is the lighting used here, kindof hard and strong on the dress and then next to none on the lady in the backround. Looks so off even that I am strongly suspecting that the lady is in fact just a picture you printed out or cut out of a magazine and put up on a wall in the backround, again, because of the difference in lighting. Like I said, like the idea, just needs better execution.
I can see this as progress - nice interpretation. I like the dress up front in focus and the bride behind blurred, but she's a little too dark, I think, and for some reason it seems a bit unbalanced. Not sure whether you need her over a bit more to the right to align better with the diagonal from the hanger, maybe?
Hopefully it was an eery effect you were going for? I'm not sure if the figure in the backround is a bride or a ghost. I appreciate the composition, but the gesture of the figure leaves me confused...what are the hands saying?
