The reason he looks a little big might be because there's so much red and black (dark blue) in the sprite, it really sticks out from the white background. It'll probably look better if you try throwing in a white highlighting and change the dark blue to a slightly lighter one, or preferably to a brown colour.
I reckon looking a little more at Arcanine's puffy tufts could help a little with the hair too. Just, of course, use a little less white.
