Opposites Attract

Remember the days when Super Smash Bros Melee was released? There used to be so many fanfictions about Roy and Marth even though no one had played their games and knew what kind of people they were. I ended up growing quite attached to the fannon versions that were developed. They turned into one of these classic comedy duos where one is and optimist, constantly bright and happy, while the other is a real party-pooper.

(Try not to mind the stupid title, please Maybe I should have put it as: Opposites Repel? No, that would only be Marth's view on the whole thing).

I'm trying to decide what kind of shading, not to mention, background I would like for this picture. For some reason I would like to see it colored.
