Basically, this nerdy librarian girl discovers Lady Death's sword and transforms into her, albeit an 8 foot tall amazonian proportioned Lady Death, complete with outfit. Shreds of her old clothing cling to her body like bits of a cocoon, but Lady Death's outfit fits her perfectly, and her glasses are askew. She's a little in shock and can't believe it.

I was thinking a graveyard as the background for the picture, at night. Maybe full moon with a skull on it, but that's optional . In my story, Destiny (the lady who becomes the reincarnation of Lady Death) is running through the graveyard being chased by a monster after waking up from being dead. As she's running, she stumbles across the sword jutting out from the ground being held by a skeletal hand. She takes hold of it and that's when she fully transforms into Lady Death.
