So last night, after a lot of frustrated erasing, I suddenly thought, "Duh! Who knows bears better than Herbie? He only helped animate the premiere bear movie of the past decade."
So I called up my "Herbie: All You Can Eat" CD-ROM and studied the "bears" section for several minutes, then went back and tried again, with better (if still not perfect) results. Hopefully tonight I can clean it up enough to make a halfway decent final inking. With the holiday crunch coming, I think I'm definitely going to have to do "Character Q&A" sketches for the next two weeks, if only because I'm not going to be home often enough to sit down at the drawing table for more than a few minutes at a time.
Alas! But I can always use the practice.
