Kirby's body seems to stretch out sideways too much, even for classic Kirby standards. Also, his idle makes it seem as if he's looking upwards-- I know you based it off the KSSU sprite, but since that Kirby has longer eyes, it doesn't give that effect.
The "mouth full" sprites look strange...the legs look too close together, but this is, in part, because you made his body thin out after the arms, instead of keeping its round shape. Kirby is basically a sphere, so the shape of the body itself should be even throughout. In fact, I'd recommend to just draw a perfect circle and append the other parts according to the pose you are trying to accomplish.
Generally, your outlines are too sharp, try to make them smoother.

Here, I took the liberty of doing a couple of edits to illustrate. Hope this is useful somehow.
