Incredible.
I can't wait for a sequel after seeing this.
The storyline was a bit short for a single installment, but I'm guessing that the contributing factor is the size constraints. Also, when the guy decides to go find answers, wasn't he looking for a job...?
Either way, this is beatifully animated and loved the effects you pulled in here, like the ghostly girl at the deathbed (possibly a valkyrie taking an einherjar?). Most stunning, although slightly choppy here and there.
Rock on.
