Decided this is finished, not going to overwork it. I added a moon and its shadow. I wanted to keep the colours fresh and interesting. I liked the idea of tipping it at an angle. We tend to have images of planets on a horizontal plane because that is the way the solar system rotates ‘on the plane of the ecliptic’, but if you were on an asteroid skimming past you wouldn’t necessarily be travelling in the same plane as the planets.
