I scanned this in and spent some time with a new program I've recently acquired. 'Manga Studio 3.0 Debut' It's a pretty coo program. Lots of gradient options but it excludes color completely. But it has it's similarities to Photoshop so it's easy to pick up. This is my trial run with it. I'll probably be testing it more later on.

Hope you enjoy his happy Mug! Or choke to death with a blast from his Ventricle arm! Gargle blood and die! Hahaha!
