In this one I think you should have made her fill more of the picture-top of the photo is just black and has no visual interest. Triangular composition is very stable.
I think with a straight on shot like this the lighting would have looked even cooler and more mysterious if it was more to the side of the subject. Either low key or high key would work (almost straight on, or almost sideways). I'd really have to see to compare though. I just didn't really realize t first that there was a snowboard in the shot haha...
