please criticize my technique

Here's something I cooked up in a pretty short time span as more of a test of what i'd be able to create by simply doodling and correcting any mistakes I saw fit. I guess it's two little sumos and one has an afro?.
I'd like some tips on shading and how I should structure my art. How do you usually begin? how do you go about shading?. See anything I could fix up?, thankyou.

hmm, to me they look like fine sprites, but not sumos.  they look like a couple of guys at the pool.  sumos are typically recognized (in the states at least) by being very fat with an abstracted happy-face and little topknot hair.

Aha. I understand. I'm sure there are a few things I could touch up on but I'm happy you think that they're okay.
