Tattoos are entirely different than anything else in the art realm. If you arnet a tattooist/havent been trained by tattooist you should probably not design tattoos. Obviously you can doodle up your ideas and say "hey i want something like this", but in the end the tattooist will re-interpret them and needs to get the final say. yeahh.
Edit: i dont tattoo at all I have just heard this over and over.
