Good, but with some flaws
There are some really good things about this animation, and then other things that really get in its way.
The opening scenes seem to have a lot more effort in them then the rest. This is great, but I'm at a total loss as to what's going on. Yes, I'm sure seeing the first part would help significantly, but its not just 'who is who', its what the hell did she just do? What was the point of this or that? Voice acting helps. So does blatantly showing something that explains what's going on.
I noticed, for example, in the opening shots of the... uh.. Japanese Zombie Planet? Anyway, the fence. You decided to tween it to give it some depth. It looks like you decided it looked too 2D, so you added additional detail to the struts, and tried to get them to match the movement of the underlying 2D plane. The tween smoothing seems to have made this difficult, so the detailed layer falls off track, and the whole effect is lost.
The fight sequence at the end had the advantages of having well drawn characters. The Zombies seemed to move better than the humans though, and our heroin appears to have been flying the whole time. Even when the badguys watch her on the monitor inside, she's STILL in the air.
Sound effects where enough to get by, but the music was very irritating (to me). I think you could have done a LOT better, even digging in the Audio portal.
I hope you take these things into consideration, and continue to bless us with your hard work!
