So I spent the day watching zBrush tutorials and being generally overwhelmed and intimidated. After quite a few hours of that, I spent the rest of the day playing.
I'm getting the gist of combining alphas and brushes... but are they kind of cheap? Like Photoshop lens flare? Better look at more professional work and figure out what's good and what's out.
Haven't done much with asymmetry with this guy yet. Let's see if time is better spent on other things.
