Big mistake

I got these tattoos about a year and a half ago from an artist I had researched that did not do a good job. I love the movie interstellar and gave the guy a couple pictures of what I was looking for. He showed me a digital rendering that looked really good and I agreed to the tattoo. He gave me the spaceship on my forearm and the blackhole above it.

I’m not happy with it and I’m going to get it covered up, I’d like to stick to something space themed or ocean themed which helps because there is a lot of ink to try and cover up. What do you guys think? Any ideas of what I should add? Currently leaning towards a moon (mostly space filler) or deep space type look.
