So, bases.
Bases are, well, a base for the position of a human. Bases also look like naked cancer patients, because most of the time they don't have hair. If bases or draw on top of, it usually doesn't look very good. Maybe because the quality of the base, and the quality of the person drawing over it, are at different levels. I personally use them as REFERENCE, a lot of people do. If you can't find a picture of the pose you want, there are two solutions. One, take a picture of yourself in the pose you want. Or two, get an artist mannequin. I got mine on amazon for $5. Ba
