Yes But I was painting since childhood so I didn't start from zero with coloring. I can't remember exactly how large was the lineart, but it was probably 11x17"/300 dpi [link] here's the original lineart in a bit bigger version.
That dude knows something Also learning all this at your own is admirable. I think I'm still far from your level, but at least I think I can reach it so...If you wish in your free time's free time you can check my poor litte...gallery... -they are kinda old stuff- and tell any hint you've got. Anyway you helped, so thank you ^^
