I really enjoyed it, and even though it's only an introduction, you get a good feel of what's happening in the story. I cant wait to see the rest of this ;) (btw, were you working on your collab parts, AND this at the same time?)
I thought the audio quality was really good, some of the VAs werent as good as the rest, but that's understandable.
Some things I would have improved on it, the build up to the end. You could have gotten further into each character, so the viewer can more closely relate with them, so they feel a certain way when they die/take over, or are introduced in general (like a character that was talked about, but not seen yet). BUT this might have nothing to do with you, because I'm not sure how you're going to set up the rest of the series XD
I'll definately keep my eye out for the rest
(ps, I fivened XD)
