Just finished this!
It started out as just a doodle of Goku's face, but I really like how it turned out. Then I started drawing Vegeta, who didn't turn out so well... I redrew Vegeta several times actually and I'm still not as happy with him as I am with Goku. Ah well. I also gave up battling with Goku's gi and decided he can be topless.
Here's a couple of closeups. I kept them reasonably scribbly because I like that, but you can tell I worked on Vegeta a little too much and eugh.
