You really shouldn't ever take this "coloring book" approach to any tattoo. If you are willing to travel to get tattooed by someone whose work you really love, why have someone else complete the work? It makes no sense and is a disservice to everyone, including yourself.
I'm currently getting a sleeve from an artist I've admired for a long, long time. I tried for 3 years just to get an appointment, which wasn't until the end of 2014. I can't go often or for more than one session at a time, but I've had 4 sessions, and there's still work to be done. It's been a long process, but I wouldn't trade any aspect of it because the end result is so, so worth it. If you're gonna commit to traveling for a long-term project, then fucking commit.
