compiled some of my favorite ink in MMA (contrary to popular belief, there are some dudes with dope shit and no tribal haha). thread bump too.
Dan Hardy (Sleeve artist: Sung Song, Upper Left Arm piece: Tim Hendricks)
Thiago Alves (Sleeve artist: Ami James, also blended in an old tattoo of a pitbull that was on his upper-arm)
Kid Yamamoto: Left arm is japanese sleeve, with a traditional americana panther on the forearm. Upper right arm is a bio-mechanical piece. Chest lettering was done the old school way of tapping the needle. His back has some sort've rose-type piece (can never find decent pics of it).
might add more. just did this off the top of my head.
