Perspective...
What's with the perspective? Did you intend on screwing it up by making the things closer smaller than the things in back? Just makes it look weird. And i dont really think "tranquility" fits. it's more like a bizarre alien world, really. Creepy music... while it's nice to make the file size smaller by using such a short loop, it gets way to repetitive for this. I guess it can be hard to make a good background and atmosphere, but this one could use some improvement since that's all it is. That kind of background would probably be fine with some other stuff going on in another flash though.
