I love how you went an entirely different direction with Excalibur, most skins i see, they are all different but they all kinda hold the same theme, that being an alien ninja.
But this one gives a whole new feel to him, he really looks like a noble swordsman, almost a futuristic samurai.
It's simplistic yet complex at the same time.
And for something that's artistic as this, i compliment you and by god if this makes it into the game, i'll be picking it up on release.
