Skull Tattoo

I already have one tattoo, I got it just over a year ago. It was a batman of my own design. Now I want another.

I've been working on a skull tattoo. At first I thought I'd want an anatomically correct skull, but that has passed. Now I want a more simple skull.

 These are not my final choices, but merely mid-points on the way to my finished project. Any feed back is appreciated.
