coloring a scanned image

I drew this (very quick - the face doesn't look right) sketch and then I tried to color it. Took me like 60 seconds, so I know I'm not doing it correctly. All I did is paint with the layer on "multiply". Doesn't look that great.

Is my sketch bad for coloring because I did a little bit of shading on it? Should I erase that? Or maybe I can make it look like it was watercolored, like supahsekzy did. How'd you do that, supah? Thanks guys.

I'll draw some better stuff once I learn this technique.

I think the coloring looks alright if you were trying to make cartoonish. If you were going for a realistic effect then maybe you should use some kind of filter(s) to get it right. Not sure because I'm not that big into coloring scans.
