Didn't have enough time for a long reply, but I can give you a few quick tips.
- Have the head bob seperatly from the rest of the body a bit. It'll look more natural, less stiff.
- Don't make the 'front' and 'back' arms mirror eachother in movement. Change a few pixels, at least, so it is less confusing to the eye. One arm lands in exactly the same position as the other. Legs do the same, but aren't as big of a problem.
- It might be a good idea to move his hair around a bit, just to add more life.
That's all for now.. Good work!
