This is very interesting. I like this one! At first glance, it makes people wonder why is the mannequin is translucent.
It could be better if ur reflection (legs) can be somehow removed. Maybe can burn the surrounding to make it all black.
Also the prada was cut half way. I think it's best to either show the full prada, or cut it all away. =)
Yes, I agree with you that the handling of the Prada sign could be better. Removing it would look good. As for the legs, I purposely leave it there as I wanted to have human elements in the photo, as the dream may have objects and people in it

By the way, glad that you enjoyed this photo. It is encouraging for me. Thanks!
