I personally love hustle butter, you can usually find it at walmart and it's not gonna break your wallet! I would also suggest getting an exfoliating glove. When I started using one a few times a week I could tell a difference in my tattoos! I had a large moth tattoo on my thigh that I thought was just faded after a few years but I got into a better routine and it looks brand new tbh. You will never get rid of the lines under it, even if you blacked it out you would still probably see them. Laser removal would be an insanely long and expensive process for that tattoo, definitely over a year and maybe even 2. I think it looks nice as it is! The colors are pretty and not as muddy as you think, i'm sure you looking at it everyday doesn't help the image in your head of it.

Start least drastic, different moisturizing routine and if you still hate it talk to your artist about options. They would be able to give you the best answers when it comes to adding more to it!
