I've found out that most of the issues with Gonzo's face is the way he is stuffed. I popped mine open and took the stuffing out of his head trying to tweak his eyes, and re-stuffed him with the stuffing pushing the sides of his face, rather than the top. Looks SO much more like Gonzo now.
Only other thing is for some reason his arms are rediculously short. Since Gonzo has such long arms in comparison to other Muppets, it really shows that they arn't anywhere near as long as they should be.
