Wow! Amazing! The tutorial you linked to is MASSIVELY helpful. That 'rule of thirds' factoid was something I know I must have stumbled through in art school, and kinda neglected, and then seeing how you use it in this composition makes the entire concept CLICK. It makes SENSE.
By the way, for your 'inking' lines on Joker, were they a single color? Or a different color that is darker than the color surrounding it?
And thanks for the tut. I don't use Flash (cause I'm slightly retarded, and it's REALLY hard for me to work with) BUT, I know that I can use all of the principles in PS. Keep a lookout for some cool colored stuff thanks to your tut.
Wha-- did you expect me NOT to try something out? LOL.
