Well, it is improved. This is the type of thing I was intending when I made the crit, so maybe this will help you see how you could do it. Primarily, the feet are an issue of perspective and depth. Other shifts are the far whiskers moved down a bit, the ear shading changed, the eye moved right, the shadow expanded a bit to fit the shape, the belly gained a more rounded shape, I removed a color, and now the fur has a specific texture that identifies it better as fur.

This is just a motion in the direction I'd advise and I tossed it up in like 15 minutes, but I think it shows what I was trying to explain with my crits. And no problem, we're all here to help each other, right? :)
ficou muito bom , mas acho que se vc colocasse as pés um pouco mais distantes ia ficar melhor
I tried to do something that you said, but did not have enough space for the left foot, but made some improvements. thanks for the help!
Nice job overall, but I think his left foot(our right) is too far under him and not far enough forward. If it was where it is now, Raticate's body would conceal most of it. Conversely, his other foot could stand to be concealed a bit more by the far end of his body. Other small stuff would be that one of your colors is just being used for a couple pixels of AA, and they don't really make a difference, so you could drop a color there, and I think the eye should maybe be moved to our right by a pixel or two(maybe, I'm just glancing at it).
Like I said though, great job, the shading and such is pretty awesome.
Very good.
