Not bad. Chest looks a lot better following the stomach. Other than possibly a few pixels on the inside of front part of the tassle on his head possibly being shifted via a bit of subpixel animation (to make the head turn/shift read a little better), I can't see too many problems calling it with this one. The only other suggestion I could make is to add a third position of the head where the face turns to (his) right a bit more, or just omitting the head turn (since, at the moment, it reads as very jerky with the face and helmet pixels suddenly changing like that.)
But you said you're done, so I won't hold it against you lol. ;P
