Outstanding picture! The lighting is so amazing and you have a very interesting subject. Great effort to get this shot. Vignette transition areas might be be a bit abrupt which makes it look like the model is standing in the middle of a giant circle, but perhaps you intended it to be that way for a reason. Best in challenge. 10!
I do wish you could have gotten all the goodness here without that shadow, it just steals all the mystic goodness form the shot. That said a very nice image, top ten
This has so much potential. I think if you had positioned the camera at a lower angle and shot pointing up a bit, that would get rid of the shadow in the background. Also I am a big fan of vignetting but not when it is too obvious.IMO 7
