I tried animating the head :\
What do you guys think? Should I have animated the first one or left it alone?
On the side views, his head needs to move, other than that, its very cute ;P
Thanks for the critiques 
@Lizard yeah, I'm not that good at animations much less full body anims. I chose to move only his belly because I wanted to create a waddling motion.
@Manupix The side views are not good at all. 
I tried to figure out how to mimic the front and back views' motion but couldn't figure out how, so I opted for simply moving the arms.
Any suggestions on the feet? 
I like the front and back views, but the side views don't work. He should move his head and / or body somehow, and the feet don't seem to do an actual walking move.
They look boring, mainly becasue you're only wobbling the belly and moving the legs. The head should follow the body.
Better :D
