I am a BiiiiG Travis Charest fan, and I can't believe I haven't shared this article with you guys yet. It's a short tutorial on how he does one of his beautiful sequential panels. I have to warn you though, he uses good ol' ink and airbrushes, no computers!
To see more of his art check out the extensive Official Unofficial Travis Charest Gallery.
I also recommend you check out his Space Girl series.
All good stuff, all good stuff.
