Great detail.

You've got a lot of detail and shading going on there, and the body and clothes look fantastic. Gives the rag-tag look and feel; good creativity with the different bits of different kinds of cloth in the clothing. Good work on the hair as well! Overall, it's a really good piece.
Two problems: The eyes. They're of different sizes, and the right one (our left) is too far over from the nose; they're off center and give the face this imbalanced look that is a turn-off. The other problem is your cropping on the thumbnail. The entire image is in there, but the image isn't square, so the thumbnail looks like a flattened version of this. Not actually a flaw in the drawing, just in your representation of it in the portal.
Good work!
