For the new animation: Head reshapes a little, I recommend drawing more of a circular shape when he looks down, he gets stiff in the shoulders too. The Banjo keeps going up also, when you play and instrument people mostly will keep it in one place. The overall actions were good and it was easy to see that he was playing the instrument. And the overall effect the animation gave was good as well. So, you just started animating, what did you use your tablet for before then? Another place to post is "The Easytoon Place". You mostly will get less comments, but they will tell you what you need to work on more no matter your skill level. Rather then saying its good or bad. DeviantART is also a good place to post your animations.
