I really like the all of these colors. I'd pick the first one if the image background is dark. I think the glowing orbs, one being blue and the other red, goes well with the violet in her costume. Good luck. Look forward to seeing her progress!
With everything in mind the chosen color scheme looks great and works with the dark background but my eyes after 4 days still really like the last color scheme(bottom right). (my preferences getting in the way mostly, nice work either way.)
