This 4 legged thing looks really nice. Did you think of a use for it?
Anyway, here are some ideas:
*Try to delete it's upper lip, and give it some nasty-looking big teeth, and maybe a rhino horn.
*It's ears look too imaginary, try something smaller.
*You should try taking on of the older versions, with the cute-looking black eye and add it to the latest version as a baby(with some modifications.
Good luck with that,
Benny

EDIT: btw, I also agree with R-Tillery about the claws.
