Custom Mario Sprites

[Vipershark]

As far as the colors go, you still have pretty much the same issues here as you did on the last set of sprites before you changed to the SMAS palette.

On that note, you need a lot more contrast and hue shifting on your sprites. Your shades blend together too much.

I can't even SEE the shades on the overalls unless I zoom into 8x.
You need more contrast pretty desperately.

Also, all your colors are really saturated. Desaturate your highlights some.

Edit- I just realized that you're using the default MSPaint red, blue, and yellow. You should basically never use the default colors, ever.
