￼I do like drawing and painting planets
This was drawn in ArtRage oils. I used the dry brush and metallic setting for it except for the moon where I turned the metallic option off. You can’t paint smoothly with it but you can get an impression of what you want to depict. The largest brush size is the size of the moons shadow, so to build up the background you have to shade backwards and forwards to cover the whole picture. This is glorified finger painting!
You will notice the top left corner is lighter than the bottom right. That is because the app is set up to have graduated shading across the picture. There is some difficulty drawing accurately on a screen with your finger, especially when the surface is apparently fluid. The result is the moon in the bottom right corner does not look quite right. The image is imagined, not taken from a photo. The moon is not identifiable but would be one of the four seen by Galileo. (the four biggest), (no I can’t remember their names!)
