Hello there! First of all congratulations on this wonderful piece. I may say that this is one of the best manipulations I've ever seen. Well, since I'm a little newbie on the critiques, don't take it too serious xD Let's start:
Vision- Although it's hard to understand what she's doing with the corpse, I assume that it's like a nightmare, it doesn't need to have a purpose. By the dark clothes and the scissor "preparing" a corpse, I assume that she's Death. I also love the fact that the corpse is flying. These elements made me give you 5 stars on the vision.
Originality: As I said before, this is one of the best manipulations I've ever seen, so 5 stars on it
Technique: It all blends together so well, the corpse, the woman in black, the light, the dust on the light, that there's no doubt that your technique is extremely accurate.
Impact: This piece had a great impact in me. The only thing that I would change was the lady in black, I think her face and hair are too ordinary. You can get easilly distracted by the other elements instead of her face, but again, I think this piece is a masterpiece in itself ^^
