I really like the style. It's super cool. Animation is great as well, and you've got a great atmosphere. It's very weird and really feels like a desert. The whole thing has a sort of dark sense of humor. The music was pretty cool as well. You've crafted a unique world all about survival. All of the characters exist within the world and they all feel like they're just trying to make it. I also love the cult, it plays into that dark but silly humor. I love how one of the birds had its beak buried in the sand. All the plain zoomed out shots help with the realism. One thing that I felt didn't really fit was the cult eating the bird. It was a bit too short, though I did appreciate the surprise factor.
Overall, this was great, both surreal and real somehow.
