When you edit this... please leave this version too. It is utterly fantastic! I adore the variations of light an dark. Greyscale is a little hard to pull off. I would love a color version, but for now. This will replace my bright and vibrant desktop. I think you did a wonderful job making her accouterments shiny and metal looking. What inspired you to do this O.O
I was listening to [link] ... I thought: Who/what could she have cast a "want-it, need-it" spell on to know that it "works every time"? I rather like the idea of Twilight as a powerful, evil mastermind more so than a psycho stalker. So perhaps she cast it on something only she could see, maybe the idea of herself as an Alicorn, or perhaps image of her ruling Equestria. Could her ambitions and magical power cause her to attempt a coup on the throne? Reign as Princess Twilight?
Just some ideas going through my head,I love the depth of these characters.
