Shiny/wrinkled tattoo

Hey I got part of my tattoo colored in about 3 weeks ago on the inner arm (it's purple/red/orange), but if you look really close the skin is cracked, and it's shiny. Also it still itches slightly. I peeled it, but I wasn't like feverishly scratching it or anything like that. I have almost a full sleeve (which I also peeled in the past, and nothing happened), so I'm just wondering did I happen to get unlucky and screw up my tattoo, or is it still healing? I hear red takes longer to heal, and also the area of the arm is more fatty. Please tell me it's still healing... although it's been 3 weeks! :X

Disregard the word wrinkled in the subject line, what I meant was cracked. Like lines of cracks vertically.
