This is Mara, a.k.a Zombie Seventy-four a.k.a +Mara Mascaro . I think I was slipping a little here because there is heavy use of the pen and less freedom with acrylic. The is an old scan too I think and doesn't really do the final image justice and a big part of me is wanting to go back to this image and give it a few tweaks.
But that would defeat the whole point of the project, so it will stay as is. I'll just have to draw her again soon.
