Cool pic - except for whatever is going on with that foot/leg stuck in the corner.
First, that is one ill-defined mass of meat. Second, dude, we don't stick anything in corners. Corners are eye-traps. It's a pity, because the lines of the hills actually block both bottom corners, keeping the flow circulating inside the picture, as desired. But placing the leg there completely defeats that purpose.
Gave myself 20 minutes to draw this pic. Spent another 20 on the colors. Was just trying to push myself to produce something worth looking at in a small amount of time. Time has been an issue lately. Oy.
