Charizard TEH AWESOME!
I'd have say that this is one of your best art pieces you have but they are all great! but like the last guy said the wing is wrong but forget that guy he can go do some unmentionable things to a donkey! I like to think of it as creativity! I like the concept of both sides of the wings being green even if it may be a mistake. btw you should do more pokemans.
Stop it!
