I think the pose is a little awkward as it looks as thuogh she is coming out of his head. It's a great idea though. I also think that there is too much blue in the photo. Maybe the white balance is off in your camera?
I like the shoot, It looks like you took time to compose it and thought about the setup well. The only draw back that I see that it dose not meet the specification of the challenge by begin a studio shoot. -5-
