Me once again misinterpreting things at first sight, this looked like Twilight Sparkle fanart. This is a very nice piece of art. The only thing I notice is that it appears to gradually get less polished the farther down in the drawing one looks. Like, the face and hair and the skin in general are very well done, but the shading on the tights and skirt is somewhat less solid in comparison to the rest, and the legs have little bits of color that made it past the lines. It could be a style thing, except the whole artwork isn't like that, so it looks a little incongruous. Very good grasp of anatomy poses, and hair here. I quite like this art overall.
