that's not me, I think about a tattoo before I get for about an hour, many of my tattoos were spur of the moment , sometimes on several tattoos I didn't even know what I was getting until I got in the chair, also some of mine were flash off the wall.
Welcome. This site is for tattoo enthusiasts. The best thing you can do is look for a competent tattoo artist and discuss your ideas with them. Ask friends who is good, look on line, go to a tattoo convention. Good artists aren’t cheap and are usually booked out for a month or two (or more).
I’d also watch a couple of seasons of ink master - fast forward to the critiques; you’ll learn what to look for in a good tattoo. You’ll also see some great tattoos and some awful tattoos. Learn the difference.
Good luck!
