Ask the person, couple of start things, as in, what colour scheme they want, do they have a character picture they want, do they want a certain style/effect, do they need a ship in it (myself I render a ship to fit)
Sometimes, a style idea they want and something they originally wanted, you might make something and they say, “oh wow that looks better”
There’s a lot of good tips in the thread, perhaps it should be pinned?
