I really like this one. A plant taking over the world and forcing humanity into the skies and underground is a fun premise, and the way you've built out both cultures from that single idea is impressive. As the sky people living off flowers and fruit while capturing gas for their airships, the underground people farming tubers and weaving roots into rope.
Also on the music side, the piano tracks were great, but some reverb or a bit of delay would be nice, "Field of Flowers" especially felt like it would've been more impactful with that kind of space in the track.
Very nice compositions!
