These were done super fast due to a combination of very limited free time and total lack of patience. I like Beth Ditto (who rules my world) the best, though I should have gone in for some more shading.
The self-portrait (with a toothbrush sticking out of my mouth) was done from a very dark picture, and I'm not a fan of how it turned out. I was going for some lazy-ass cross-hatching, and the results were lazy-ass messy. Some sort of balance between the two and more precise line-work is needed. But all in all, not bad for a start.
*I could pretend I did these the old fashioned way with ink and paper, but I'm all for honesty in art. And, as a certain friend of mine once said, "Work smarter, not harder, stupid."
