Jokes aside, it is a nice try!
Being unsatisfied with the result means you can see your mistakes, so you can improve your skills. Just don't give up. Keep it up! :>
Eh, it's a decent try. I mean, it resembles the character at least. And there's far worse Wario fan art out there (like that old Kat cosplay that gives people nightmares). And hey, your next project will now be that much better, since you can learn from this one.
