I assume that I didn't explain well enough what I wanted...that's probaly my fault.
Sometimes, I really like to challenge myself and some years ago I tried to color a manga I loved "Air gear" (just 3-4 pages), obviously I failed lol
I wasn't good enough, but now I feel confident to do something like that.
Well, air gear ended, so I was searching for something with epic moments and well cleared. Not a lineart with pure black lines, but not even a pixelated JPG image.
And for linearts, somehow I don't really like traced linearts, like the one from a manga, dunnoh why.
Just name the first manga that you would like colored and is well cleared, don't waste time over it.
