More neck! :)

These are beautifully expressive! :D One thing that I've been working on in my own gestures lately, that I think might help you: curving the ribcage to show the motion better--like designing the contours that Stan talks about in his Step-by-Step gesture video. My words fail me sometimes, so I attached a picture in case it's a better explanation. In any case, I really like looking at your work!
