That looks incredibly hot. I wouldn't change a thing. In my experience when people start monkeying around with a tattoo, the make it worse way more often than they improve it.
There is a difference between simple and boring. Yours is simple, but not boring.
Just wanted to update, because it's been a year. As @Hogrider mentioned, it took almost a full year for the colour to settle. It just recently started to look as smooth as the black/grey work. Time works wonders for healing, as is oft repeated here.
You can't pull ink out unless you're lifting scabs, and that's not happening with your tattoo. The above looks normal for a tattoo that still needs at least 3 more weeks of healing time.
They just look like hair follicles to me. Your artist probably shaved your leg, yes? Could just be hair growing back and you're not used to seeing that, especially if you don't normally shave. Leg hair will always be visible over your tattoo, ink doesn't hide it. I'd wait a few more weeks then try exfoliating gently if ingrown hairs appear. Don't exfoliate unless your tattoo is completely healed. But I wouldn't be concerned about this one bit.
If they don't itch, hurt, ooze, smell then no, not at this point. If they are still there in a month or two I would go to my tattoo artist (don't call or email, go there in person) and ask them. If they don't give a satisfactory answer, go see a dermatologist.
