Check out lu_skywalker on instagram. He can do photorealistic work quite well, and does some really rad color blocking and shading in all of his tattoos. He’s also pretty good with revisions before the appointment. I’ve always gotten sketches a few days before the appointment.

I will say, paying additional as another poster suggested is also a good bet. Tattooers work a ton if they’re good, and extra revisions are time they’re not tattooing.
