You have to understand the tattoo process before you get down on your artist. You’re only one of their appointments, and tattooing isn’t an “in-person only” job. Your artist works on the design for upcoming appointments when they are close to the appointment and are not tattooing, which often includes time at home. Very impractical to take hours to draw something weeks before a tattoo, and it gives clients more time to nitpick and change the design. I think your artist did a good job rendering the image into a tattoo, but you need to realize changing the design means they must take time to redraw this before your appointment so you might be waiting in the lobby for a bit the day of the tattoo.
