For this project I decided to go with mountain landscapes. I had a good time messing with colors to create something a little different. I also generated stars in the sky. I decided to make the stars transparent so they were more subtle and you could see them pass over the moon. I also made the objects further back move slower so it would imitate what you see when you look out the window.
