Tattoo advice needed

[rok21]

I got this tattoo back in November. I had it touched up in mid-December from the same artist and it still looks like this. You can see on the “N” that it almost looks like my skin is coming through the ink on the right side. Is it time to get it touched up for a third time but by a different artist? The missed ink is very noticeable. Thanks for your help!

yeah, it doesn't look real saturated - but the line-work is nice

Just get it touched up again.
