It has an awfull coloring!
He looks uncomfortable, like he's having difficulty breathing. That could be okay if he is meant to look very old, I guess. I like his eyes.
great design, not so good animation.
The animation is a little strange, but I love that blobby feel... And I think the colours are nice... Looks like a cross between that FUTURAMA squid guy (wont remember its name now) and that green swampy villain from HE MAN.
