Some really nice touches
Sound, really good...
Animation was good at some parts, others not so much.
The part at the beginning...the clouds looked weird...some were moving up and other down and made no sense :P, try fixing that...
You can now blur stuff at Flash 8 so... don't import images with effects, makes the images to have low detail and look different from everything else ;P.
Well, other details...some fbf were totally detail free...when a guy turned around he didn't have eyes and then they just appeared >_<...
Other than stuff like that...it looked really cool... good job
