This is an amazing photo! I love the position and the colors but what concerns me is that the model, in my own opinion, is wayyyy too skinny. You can count her ribs and that can't be healthy. She needs to put on more weight.
(i'm tired, so this may not come out as i mean it) but i like how it's sort of reminicent of queen elizabeth I, i'm sure it was intentional, you did it very well. the model is perfect, and the lighting too.
