Hey everyone! I posted this in my sketchbook a little while ago, and it seems some people found it helpful. I just remembered we had a tutorial section, so I figured I'd post it here too! It's more of a process breakdown than a step by step tutorial, but I hope you guys find it helpful. Lemme know if you have any questions.
UPDATE: Just wrote up another step by step, walking through a different process for drawing characters in photoshop. Let me know if anything is unclear
UPDATE 2/03/2012: Just adding another tutorial I've written up here on my King Dodongo piece.
ALSO: For those of you interested in brushes, there are some great sets at this link, all you should ever need.
