Ghostly Characters Tutorial

Warning: This is a pretty big pic, for those who have a slower internet connection...

Making tutorials is fun - exhausting, but fun.
I wanted to show you how I made Guybrush appear like a ghost in my latest deviation ([link]). Hope you are interested and this tutorial will be useful.
Of course, this is only the way I did it. I'm sure there are other ways to draw characters with a "ghostly appearance", too.
I'd love to do more tutorials like that some time, but for now, I'm out of ideas and time for doing so.

EDIT: Oh, something I forgot to mention in the tutorial: I didn't shade the "ghostly" Guybrush, because ghosts don't cast shadows, and I think that applies to the shading on the ghost, too. But I hope that's clear.
