I think this is a fantastic redesign, and there isn't much to change except for the usual--figuring out he proportions. Everything from the knees down look a bit stubby (or short) and there's a small wonkiness in the right (our left) eye and this could all just be solved from continuing to draw and perfect your craft ^^

Also the shadows could be a darker value so they don't add much emphasis as a shadow ^^;

Good work though !!!
