The Intro is a really nice subito segue into the main subject.
The 60 second mark of Alces is the most Gen IV sounding thing I've heard in a long time. Not a bad Gen to sound like, if you ask me!
Caluar & Aves feel a little bit less fleshed out than Dylidae and Alces, but this is a detailed, clean, and stylistically consistent collection of material you've put out in such little time! Excellent work.
