I'm torn.
On the one hand, I love the lighting. It's moody and ethereal, very beautiful and very Calvin.
On the other, it's almost too shadowy. I would've loved to see those barely there shades of nude and chalk white.
Plus, as Dale said, the pose is awful. A beautiful, linear column like that needs to be shown in it's full glory, tall, statuesque, graceful....not slumped back and open-legged. She looks like it's been a hard night, and who wants to look like that?
