I didn't get to your photo in the voting. There were a lot of entries. I think it is an original and creative take on the challenge although personally, I don't care for set-ups with titles like this.My feeling is that without the title and the challenge subject the photo doesn't make much sense. I believe a good photograph should be able to be viewed, title-less and outside the DPC world and still make sense and appeal to the viewer. These kind of images never makse sense (to me anyway) outside of the context of a DPC challenge.
It was a good effort in terms of composition and technical details (although I tend to be better with the composition then the technical stuff myself). The subject needs to be further away from the background to avoid the shadows. That, and directing a light just on the background effectively eliminates shadows.
I didn't comment, but I voted your photo a 9. I thought it was one of the more creative shots in the Challenge. Perhaps (this is just my opinion on how the site operates) it was too creative.
Very well done!!! A very good use of shallow DOF (as opposed to blurred background like many of the other shots.) One of the more creative shots I've come across so far.
