Wario and Waluigi RPG sprites

[Ninspriterx]

If you're still talkin' about fixing up Wario I can point out a few things.

First is color! Those colors look dirty, which is bad considering how bright and colorful the M&LIII style is. You should try out things like
Finding a more saturated or "truer" yellow, and have the darker values hue more into red instead of straight to black.
Only sparingly use shades. Go over it again and if you have to ask yourself if more shading should go somewhere the answer is no.
Of course you can always use colors from the original palette. I would even suggest using Bower's yellow, and the Shroobs' purple.

Next is the overall design. From my experience M&L is just big enough to put a lot of character into the face. With Wario, he has a pretty big and wide face. So you should start of with a bit of a resize because right now he looks a little squished. As you can eye-ball it here Wario is a little over two Marios in legnth!

This is all I could think of for now. I distracted myself from doing homework.
