You don’t want to kill all your dark areas they are very important. Just make little strokes like that. There isn’t a rule. You just practice and find out which way works best for you. See. We take the corner of the brush and let it play back-and-forth. Get tough with it, get strong.

I spend a lot of time walking around in the woods and talking to trees, and squirrels, and little rabbits and stuff. If what you're doing doesn't make you happy - you're doing the wrong thing.
