I think he's perfect. He's pretty detailed as is. It's funny how in most toy lines, CARTOON ACCURACY is what the fans plead for, lament over, or their "holy grail". Not so with MOTUC. If a figure is too detailed it's called "anime", or in this case, too cartoony. I think they should rechristen this figure MP-01 Fang-Man, the first masterpiece*.
*Like the TF line, that strives for detailed but cartoon accurate figures, even though the toy line came close to a decade before the cartoon.
