That's some beautiful ink work and definitely my kind of thing, only nit pick for me is the spiked collar, I'd prefer to see more or not all...she's very pretty and awesome hair colour too
Wonderful image... but... I'm going to go against the consensus thus far - I didn't actually notice the collar until it was mentioned, so no biggy for me. But I do find her eyes look a little 'Bella Swan / Edward Cullen vampirish'... They don't look natural. But that's just my opinion. Certainly not a deal breaker. I'm not normally a fan of tattoo's on display, but that really suits her, and you've photographed it beautifully in her pose.
agree with that, took me a while to figure out what that was.
