Some of these aren't terrific, but that's not the point. I try to draw just to draw. Quantity over quality makes for better practice. Plus the colored pencils I used on the Pilostyles, for instance, were real shit quality (Prismacolor on the others). I use a tombow soft tip pen for the outlines, which you can refill with waterproof India ink for a few weeks until the ink quality finally fades and they shit the bed.
