I'm really glad Shinzui didn't go the moe/genderswap route and chose to remain rather close to history. Kudos to the artist, he fucking rocks.
The awesome thing with Napoléon is that he could be an Archer (with the Grande Armée somehow being like the Gate of Babylon or Golden Wild Hunt's cannons) as depicted here but a Rider as well, since Marengo was the Emperor's most renowned horse, kinda like Bucephalus and Alexander.
