Morning! Very sorry for late response, but due to vacation and sorting my life out I haven’t been able to answer you. But if you still need an reference I’ll try my best.
When it comes to fenghuang/phoenix motif i only have 2 artist i can think of, Horimouja and Katsuhika Hokusai
As a tattoo reference the only one i found right now that i actually liked was this one. I mostly see fenghuangs portrayed in backpieces.
Most importantly you should get an tattoo artist thats specialized in these kind of themes. Good luck mate!
