Not bad, I can see improvement in your line work and colouring.
I would just suggest making Maxie's wrist a tiny bit bigger, as it looks a little bit small when compared to the rest of his body.
As well when using motion tweens, there is a way to have them come to a smooth stop as opposed to halting immediately.
Near the tween menu, looking for the menu with 'ease'.
-Having it ease in means that it will move slow at first, then accelerate quickly.
-Having it ease out means that the tween will start fast, then slow down before the tween ends.
Hope this advice will prove useful. :)
Good work man!
