Theres something very wrong with the man. It pops too much. It looks like you've used flipping for that animation. Is the head front view or back view?
The pumpkin is pretty good. But the pumpkin should have more frames with circular shape. It should not be cicular on the way down though. Thats what i think when you consider basic animation of
ball going up and down, its stretches at the bottom when going up, and stretches at the top going down. So have the U shaped one on the way down and the O on the way up. Also when it squashes
on ground maybe make it fatter.
