Sweetness.
I... wow, awesome.
First and foremost, the narration was truly excellent. Good pronunciation and anunciation, excellent tone for drama, and variability. Even when using Hood's voice the narrator was perfectly serious. A+ voice acting.
The rest of the sound... superb. Well chosen, well used. The graphics were gorgeous and fit well to the style. I'd like to offer some constructive criticism but there's really little I can see to give. Fantastic work here.
