Looks incomplete...
I think you could've spent some more time making this. In the end the sound just misses, I mean: you see a helicopter but you didn't put in sound so it looks pretty lame.
The graphics are awesome, really good. That is the reason you get a six overall.
Finally I think you might wanna look at the point where the missile comes uit of the helicopter and flies into the eye of the monster (or whatever the hell that is ^_^) The movement seems so childish. I think you could do a lot better. For example, a missile gains speed after launch. And if you make it change direction, make sure the head of the missile point in the right direction, not just move ur image up and down!
I've seen the rest of your work and I think that's the reason why I'm so though on you, just because I know you can do a lot better.
On the whole this is better than most movies on NG so you get 4/5 from me.
