I didn't see this in time to vote on it, but I did go and have a look through some of the entries even though the voting had closed. I think this one is certainly one of the best because I feel that while delivering a serious message it has a certain poignancy.
Art is, of course, subjective but I thought that the majority of the other pieces I saw didn't 'say' anything. There's a massive difference between putting together a collection of images in a pleasing way and being able to convey something by that arrangement. If it's any comfort, to my eyes your whole body work achieves the latter.
