When I saw the face, I recognized the drawing style. (I'd suggest trying to experiment with different facial structures since a few of your girl character's faces look nearly the same). The character herself looks beautiful and well drawn; she appears to be thin, a mid-teenager, and may even be an athlete of some kind. The face in particular is great. The shirt reminds me of a futurist tech timeline or something from torn while the wrappings on her arm remind me of something from a survival setting. The background looks like she is standing in a vortex that is moving passed her, with a small mist gathering about her legs. Very good job!

Wow. Very nice. I love it!
