I started a sketchblog on January 1st and my goal is to update it daily for the rest of the year. To make sure that I don't draw things that I've sketched a hundred times already, I'm going through the Marvel Universe Handbook alphabetically and drawing each entry. Once I'm done that I'll move over to DC's Who's Who series.
I'm pretty happy with what I've produced so far, and when I've got time I'll post some of the better entries here.
