I've charged anywhere from 20 to 80$ for tattoo designs. It all really depends on the size, time, subject matter, and materials you use....
What exactly are you looking to sell?
people have requested my traditional work and digital work.
I've been requested to make tattoos, portraits, t-shirt designs, and now my school is asking me to design the prom tickets since I already designed their school sweaters.
Idk, I've been doing this for free too and people have felt that I should be paid, but I don't know if I'm good enough yet.
