Scrawls, sketches, and chicken scratches - a doodle thread

I... didn't actually know that about Loomis. I guess this is what you get for briefly skimming and only looking at the diagrams. Sorry for linking that.

Copying other people's art is certainly useful, especially if you're trying out styles. I'm not sure if doing it completely independent of any other method would help beyond a certain level, but it would definitely work as a starting point.
