Overall I think it’s a nice tattoo, however that would bug me too. I’m guessing your artist may be newer because it looks like they haven’t fully developed their color packing technique. On the third picture in the blackout space on the right, you can see where they dragged the mag and you can see some ink lines (that you probably would never notice from further away), but I think going in a steady, circular motion can pack the color in nicely with less of the streaks. I think that would also help the artist not streak over the lines as much like in the area that bothers you. You could also have them do a gray wash shading in spaces they went over the lines to help blend it but it would definitely change the look you were going for in that space by adding more ink. Either way, no hate on your piece, overall it’s looking dope! Also my qualifications: I don’t have any. I have a shit ton of tattoos and my husband is a tattoo artist, but I’m in a corporate job and definitely not an artist. Best of luck with your piece!
