Welcome. ^^ Itīs not! Believe me, that Iīve seen (and made) all the possible flaws that can be done when developing own style. Yours is just original and it doesnīt even bother the eye (which happens with some other styles.)
It's really hard to bring expression to a character who has no face (how does that thing eat?), so I try to make his hands and body language do the expressing of his emotions. I like to think of Opey as the world's most human weapon of mass destruction.
