This is awsome! More Puella Magi, historical figures! Who else was there: Joan of Arc, Anna Frank, who else? It make you wonder, what kind of powers they had, and if they decided to die when they learned about they final fate? I bet people like Joan of Arc would rather perish in flames, than be turn into a monster who would kill people. I think that they all choose their own destiny and they didn't give Kyubey what he wanted.
I don't know if you've heard of it, but this kind of reminds me of Cleopatra in Space. I really like the perspective on this and the hieroglyphs in the background are quite stunning, especially how its gold shine is radiating of her.
