First piece of My Little Pony: Frinedship is magic fan art in my gallery! Am i cool now?
Have you ever watched horses fight? It's pretty intense. There's biting and kicking and stomping and running after each other and running into each other. They're big, heavy animals and they use every inch of it. Now add pointy, stabby things to their faces and wings and human intelligence and jealousy induced madness and things just get that much worse (or better).
Anywho, I thought I'd take a stab at depicting the epic battle that took place between Luna and Celestia 1000 years in the past. Luna hasn't quite fully transformed into Nightmare Moon yet (or just hasn't gotten her fancy armor), hence the darker coloring.
