lalz, I remember Super Buu Gotenks and Piccolo absorbed being the villain in DBZ I watched the most when I was little, since that was the only DBZ vhs tape I had at the time, so I decided for old times sake to doodle him
Personally, I just don't find humans fun to draw to be honest. Mostly cause I feel you can do so much more with the visual design of other things than you can with humans. I mean, you can give an animal any kind of detail a human has and then some.
I do draw humans, however, but usually not without giving them a huge animal buddy.
