Looks great! The face is really good :) but the arms are odd, looks like some sort of tube rather then a organic shape :S. I think you should have gone for a background. A little edit over my other edit xD. I think you should go for the real big thing so you can actually practice anatomy and proportions + background and shapes :) they are so kewl to do.
Well done tho, way better then the previous version ^^
