I went full colour. Once I came up with a simple colouring technique for myself.
Looking at manga, I actually find black and white intimidating. I mean, doing it well. There's alot going on in some manga pages, with the crazy detail, tones and inking and sometimes shading, sometimes not. =/
I mean, looks at this page! Why is Al fully toned, but Ed just flat, I don't know, but it works really well! The barkeep is popping out of that BG so well, and all that hatching! =p
