Bloody hands. Unusual hand poses without adequate reference always worry me. I keep expecting someone to jump in and tell me the thumb is on the wrong side, or that I've drawn two thumbs, or no thumb at all. Bleah.
OK, well, good enough for now. Now I'm starting to eliminate extra scribbles and otherwise clean up and correct. I'd like to keep the energy of the original sketch (without keeping the extreme sloppiness of the original sketch), but it's always hard.
Once I have clean line work (more teeth-gnashing), I'll probably try to color it (much more teeth-gnashing).
