Overall, it's beautiful. The body is well proportionate to the arms and the color schemes work well with eachother. the hand angles are appropriate. and of course it's on notebook paper, but notebook paper is awesome anyways and it doesnt take away from the piece, especially since you were able to distribute enough color onto the paper so that it didnt come out to dark, but is was able to overcome the lines of the notebook paper. shading is distributed accurately and in the correct places. since im not much used to seeing your style, its hard to say if there really is anything wrong the picture, especially since it differs so much from my own.
