Well this is what I did on Friday 3rd and Saturday 4th. I started out with lots of diagonal brush strokes, knowing I wanted to do large planet. But bright colors, psychedelic colors. Then came Saturday and time to make it into a planet, had to actually make it a perfect circle or it would drive me crazy. So.. redrew it , not perfect but will work, then did a dark sky and speckled stars into it. (Yep with a toothbrush) But not sure where to go next.
