Nice work.

Couple things I would add, though don't detract from your video at all.
At one point you say about Mitron being responsible for aquatic life and Loghriff for terrestrial, and say we don't know who would be responsible for airborne life? Maybe I misunderstood what you were saying but surely that would be Hermes/Fandaniel?
And secondly, there's a few other nods to FFVIII though enemy models and animations. Voidwalker is in fact a recreation (and reimagining) of the Elvoret/Elnoyle boss/monster from VIII, and the model for Eden's Promise (I don't think you mentioned this but I may have missed it) is heavily based on Ultimecia's final form, right down to sharing many of the same spell/ability animations. Not a huge deal to have missed them, but they're cool details for the more perceptive FFVIII fas.
