Turbo from Sonic The Comic

I don't know the character. But judging from the image ypou provided, I'd say your sprite lacks the distinct triangle on his forehead, the helmet and the tail. Also, you could put more contrast on the yellow (and use hue shifting).
Point is, if you're going to make an edit (which is worse enough in itselft) to make a character look like another, at least do it properly and don't put it down to a recolor when that's really not what you want.
