If we're gonna walk though the woods, we need a little path. No pressure. Just relax and watch it happen. If it's not what you want - stop and change it. Don't just keep going and expect it will get better. You want your tree to have some character. Make it special. There's not a thing in the world wrong with washing your brush. We'll do another happy little painting.
You have freedom here. The only guide is your heart. Trees live in your fan brush, but you have to scare them out. You don't want to kill all your dark areas they are very important. It's a good way of getting rid of all your anxieties and hostilities. Let's make a happy little mountain now.
