1stly, your reason for getting a tattoo is not that unusual. Go for it.
Good that you're doing plenty of research.
I'm not personally a real fan of most tribal, but at least Pascal in that particular shop seems to be doing better than average.
A picture of the actual mark and scars would help the tattooists here make an opinion of how hard this might be.
Lastly, don't worry about "not being creative". That's part of what a good artist is being paid to do. Go with your ideas, references and deposit and discuss what you want in detail. He will draw something up and you two can tweak it if/as needed.
