That's interesting because here's something I quickly drew with my left hand. I signed it lefthanded to show that there's not a lot of facility with that hand. I've found that I've got to make short quick strokes to make anything look reasonable. An effort to sign my name cursively was completely illegible. From a lefthand control standpoint, I've probably got no more dexterity than a 3-year old, but I've got an adult's eye for what I'm trying to draw. The thing that's funny about the sketch is that it has a sort of children's book simplicity to it. That's not what I intended. It's still almost something worth exploring more if I had the time.
