OMG, lineart is a biatch. D: You just have to scan pics at a huuuuge resolution (like 300dpi) so your lines don't look so wobbly. At least, that's what I do. Having a tablet helps a lot, too.
I read a lot of tutorials, but never follow their advice. xD
LOL, I don't know if one could "learn" to draw anime.
But other styles, maybe. :3
Just, get a devart account, watch the art gods, and learn from them and stuff.
