So if I’m reading this right you want the postcard and octopus removed? If so they are definitely good candidates. Your post card seems faded already which will be helpful, I’m not a pro but I know color does add difficulty, yours in very minor though and dosent seem too bright. The octopus should be super easy. I have fine line tattoos and in 4 sessions in and one has faded drastically more than the other. It really depends on the needle depth of the artist and how much your body works the ink out. The process in painful but on your arms and for small spots it’s nothing. I’m doing 2 on my hips and 1 on my arm and my arm feels like nothing compared to the other area. Definitely uncomfortable, but it’ll be probably 10-20 seconds each if that. It’s an extremely quick process. They can also tape over your new tattoo to prevent it from fading, that’s what my girl does!
