Great photo, like the lighting, the pose and colors work, shows off all the good points. Eyes in some shadow work on this I would say the look is if you can handle this walk over:-}
The light is perfect here and so is the upper half.. but it's the legs I have an issue with.. they go down and get lost somewhere and then get cropped off very awkwardly.. and I think your eyes get slightly lost in the shadows.. but these are just issues with this particular picture.. other then that I think you're up with a great set up and a lovely model :D
