I plan on doing something similar to you, but eventually covered most of both of my arms. I have to save up a large amount of money or just do some of the more simple tattoos first. The first tattoos I want to get are the word "Relentless" on my inner left forearm and "Vita Brevis, Ars Longa" on the inside of my right forearm. Hopefully that isn't too long for that space...
