Split the art in half down the middle. And again vertically, so there are four squares. Each side will have the same size and shape of a planet, but the left will be during the day and the right will be during the night. The sky is lavender during the day, the sky is deep and a dark purple at night. There are forests snd oceans like Earth has, but there is no sun. The light comes from a nearby Nebula, and at night it uses the three moons as well as the Nebula and the planets bioluminescence. Because of the vegetation and water, the planet has a similar look to Earth, only with a light or dark purple tint when the time of day alternates. Make the top left square what the whole planet would look like during the day, and do the same on the top right square but during the night. Bottom left square should be what it looks like to be on the planet during the day, same goes to bottom right but during the night. See more
