Hey Joe, looks pretty good so far. Isn't Maya great!
I think when he pulls back for the first punch, his whole body could anticipate a bit more, especially his head. I haven't watched any boxing references so I guess I wouldn't know for sure, just going on my initial reaction. I think he punches a bit too fast as well.
And then keep the body moving after he kicks as well, and don't forget about the face! (I know, not done yet

)
