Have you seen RASL? It's the current project of Jeff Smith, the cartoonist responsible for one of my all-time favourite comics, Bone. RASL is a very different beast -- a sci-fi adventure with a decidedly more adult tone -- but it's gripping stuff, and Smith's visual storytelling has probably never been stronger.
Anyhow, long story short... I definitely recommend checking it out. It's actually been running for quite awhile now, but since a new issue of RASL only comes out approximately once every two centuries, it won't take you very long to catch up. Just be prepared for the painful wait for the next installment!
