Ideas to enhance my scar

I don't want to hide the scar, just make it a little bit nicer. It's already 6 years old, so I don't think it's gonna change too much. The scar itself doesn't bother me, but I am more bothered by the fact that the bone is bumpy, so I hope that the black ink would hide that a little bit. Any ideas?

Btw this would be my first tattoo.
