Wow this is gorgeous! Wow this is a beautiful version of Death! She is one of my favs, it just turned out so well! I love the cross hatching on the shirt and the glimmer to the Ankh. The eyes and lips are outstanding, the eyes are so beautiful and haunting.
Haven't actually read Sandman. I might do because of this particular rendering by you. She's quite attractive and I believe she's wearing an ankh pendant unless I'm confusing this with a similar symbol.
So in short she like many ladies drawn and colored is hard not to stare at it.
