Basically all I did here was paint the background semi-transparently. Oh wait - first I did some more adjustments to the colors. Going with Xia Taptara's advice to start @ around 30% opacity for sketching things in loosely, then switch to very opaque for main painting, and then back to nearly transparent toward the end for sweetening.
Mainly just sort-of covering up some of the pencil work with translucent layers of transition color. Keeping everything loose and rough - I want to try to keep the energy as long as I can. Man, starting with a pencil sketch was the shizzbomb, diggity!! The shadows are close enough to black, something I have so much trouble doing digitally. And the whole thing just vibrates with energy!
This is probably about as far as I'll go toward smoothing it all out - it's just a sketch.
