I've been following the Comic Twart blog for a few months now. I think its awesome. Each week one of the many artists who contributes to this blog posts picks a subject. For one week all the posts are sketches and drawings of that subject. Subjects are usually comicbook related, everything from superheroes to. Characters from pulp magazines.
This past week's subject, Lone Wolf & Cub, has by far been my favorite so far. The drawings posted have been truly inspired works of art. Usually there's one or two that stand out. I do my best to analyze them and leave comments indicating what I like about them. I left a lot more comments than usual this week.
