Allari the Souleater would be pretty neat. Really, any WoW Demon Hunter would work I'd think, but I lean harder into the Blood Elves.

If just the back of neck and shoulder works, then I will throw out Revy from Blacklagoon. Its more of a shoulder tattoo, but it goes up the back of her neck as well. https://pm1.narvii.com/5920/f33b1e203c4915882d7908dd5dcaf341a4deba06_hq.jpg

Benisato from Ninja Scroll. Her whole tattoo is a snake that comes to life and will kill you. All the official images I can find of her back tattoo is her facing away while the fan art has her back facing you while she's looking at the viewer. https://pbs.twimg.com/media/DgA3e5SUcAETXE0.jpg
