Its mario/sonic/mickey mouse

 That's hilarious :D "That's no good!"

For the background, you could have done the disney castle, but instead of pink make it sonic style :p.

I like how this turned out! The combination of the two!

Hehe, Alex, this ain't Mario Bros :D Nice toon there, much improved from the WIP *kudos*.

 Thanks, guys... i really wanted to do more with this piece, but i felt really bad because of the flu, and the deadline was close!

Hahha coool!

Aren't ? blocks and mushrooms mario though? Maybe something like steamboat willie in the background as well as the Sonic chequered landscape.

 Getting there... the background is too much Sonic though. What about adding a ? block or mushroom or whatever?

Pretty good. I love his mad view.

This creeps me out for some reason XD

Nicely executed, though.

Great work there. I really like it :D
