I don't suppose this counts as art...
I've already posted some of my artwork ; I'm pretty good with sprites too, so if you guys have any requests, I'll be happy to make one for ya. I just thought it was funny, and I put some work into it. Mario's pretty angry in this pic. :)
I took 4 copies of Wario's arm and translated the colors accordingly. After that, I just thought up some funny scene.
(Just in case, credit goes to Frario and Starpower for Waluigi, Satoshi for Yoshi, Bacon for Wario and Mario+Luigi goes to the shirt ninja)
