I find that unfortunately schools can't teach you everything you need to know, and they charge way to much to do it. I think I might attend a night class one day just to see what it's all about.

Do you guys have any favorite books or resources you use? Or do you just keep practicing?

I find it really helpful to draw things 3 times before coming up with a final copy. Like how writers will do a story arch tree and then a rough draft and send it to editors to polish. Every time I try and make it a little better.
