Fixed the direction of the shading to make a bit more sense based on feedback.
@wolfcoder You mean make the difference between the different shades of a given hue less linear? I'm used to picking colors from the NES palette, so actually having freedom in picking arbitrary colors and still making it work is something I'll have to figure out and learn.
@NovaSquirrel yeah don't worry. Color choice is almost entirely its own field in art, you'll figure out your favorite color ramps soon.
@NovaSquirrel I'd increase the contrast so its less linear, and make the line art a bit darker and you'd be pretty much right in the early SNES style.
