This is fantastic in so many ways. First, awesome work and very beautiful forms. The sense of action is terrific with those mid-leap poses. It's scary to see lithe little Twilight so ferociously angry (and perhaps at herself too) while going for the jugular full force. Celestia's evasive action is great, plus the magic to deflect her (hopefully), though at the same time I think her heartbroken expression is priceless.
