congratulations!! this is my favourite by far - so many of the other winning entries are horribly contrived. works well on many levels - tone and colour, choice of depth of field and concept, but for me, it's the composition that is so arresting - brilliant!!
i struggle to find anything constructive to comment on with this image, and can only come up with the suggestion that, if you're going to be photographing alot of foot shots (ewww!!!??!), it is a good idea to get your models to remove their socks some time before the shoot, so that you don't get those distracting sock marks (which actually add to this image anyway)
