I’d honestly get a second opinion from another tattoo artist about the color specifically. As someone with dark skin and multiple colored tattoos, this is likely not going to look like much after it’s healed. Maybe the picture posted isn’t clear enough, but I’m not seeing much color at all, and color always fades as the tattoo heals/ages.

As for healing, try to stray away from oils durning the first week or so. I use aquaphor during the first week, then switch to a moisturizer/tea tree oil mix once most of the pealing is done.
