I really do love this artwork. There isn't much advise to give here save two. For one, I would have lightened up the background. With so many dark colors, the background is too much. I would lightened it or pale it a bit. The texture is nice though.
The second is about the effects used on the crown thing above her head. It does look amazing, but there's too much. It's really hard to tell what's going on right there. I would thin it out.
Other than that, this does look amazing. I think the piece has a lot of personality. The shading and highlighting is different, but it's a good different. It's definitely original. I love her expression and the details. All in all, I think this is a really good drawing.
