quite good

Very well done. arouses interest and created suspense for the finished work. I'll look for that
keep on your good work

nice

this is good because it dosnt explain what will happen in the thing out of place it dosnt really explain and the fact you dont see the alien is good to looking forward to see what this becomes

A unique style

I've seen a fukload of flash content before, but never anything in this style.
Its not bad or good, its simply "alternative"
Frankly, to your credit, I've seen much worse sh!t, on TV.

So you've done well.
I'll keep an eye out for future submissions.

mmh..

Depends on your style, but..

- use line instead of brush tool to draw, lines and edges looked weird on your submission

- create symbols and use tweening, it looked like you used only keyframes on every frame

If you use frame by frame style then forget those tips :D

It looks alright.

It's hard to judge a Teaser. The graphics and sound were good.
