I can feel my tattoo lines?!?

Wondering if there is anyway to settle down the lines since they are still slightly raised even after a year. I suspect it could be scar tissue, but it only appears to be raised on my outer bicep. My chest and forearm and inner bicep healed fine and are now flat. Not sure if anything can be done, but feels kinda cool I guess. Do you guys notice the raised lines, if not then GREAT😄? 

Also wanted your guys opinion on my entire piece. All critique welcomed😅(Forearm still new in this picture and not yet completely done).

looks like nice work to me! 

I wouldn't worry about the raised lines unless they become red/sore. 
This question comes up occasionally but there doesn't seem to be any practical advice or solution (or need to worry).
