I went to look for tattoo images online, to see their characteristics... this website has some pretty decent size pics:

What I'm noticing a lot with more modern tatoos is that the colors are still vibrant and not very blurred, but skin pores and their mild bumps are still visible, along with a tad of the darker pore discoloration. Especially through lighter colors.

The specularity and shine is that of the skin, it's not changed by tattoo's presence.
The older the tattoo, the softer (blurrier) the lines, and the more color shifting it has. Probably has to do with quality too. :)
