With something so strong, a little bit can go a long way.
They're not all perfectly straight. Not every limb is perfect. Even the worst thing we can do here is good. And maybe a little bush lives there. It takes dark in order to show light. It's all a game of angles. There is no right or wrong - as long as it makes you happy and doesn't hurt anyone.
When you do it your way you can go anywhere you choose. If I paint something, I don't want to have to explain what it is. This is your world, whatever makes you happy you can put in it. Go crazy. Use absolutely no pressure. Just like an angel's wing.
