Hey bro, lookin good I’m not into tribal art on myself but I like looking at others work. You sure went all in for your first tattoo and didn’t go wrong with art or artist I’d say.
Others have answered your question, but I would’ve definitely told you to stay with that artist if you were happy, changing in the middle of a project would probably not deliver the outcome you wanted. One artist one style ..
i have 8 tattoos plus my left arm sleeve and I was worried like you were in the beginning, but I don’t even think about it until around 3 weeks for a truer finished product. I just use a lotion with a skin protective active ingredient like lotion from hospital, keep it moist but not overly as that can bring out the ink from my experience. I normally use lotion twice a day until the peeling is almost done then once a day after showering then when needed once peeling is done. Also shaving the hair off will give you the true look oppose to having a slightly distorted look from hair being over it. I shave my arms only after it’s healed about once every 2 weeks so they look the best. Good luck to you
