Not so great
Coming from a 3ds max background it was rather.... Iffy on what I should say and how I should review it. You had some goods and bads but mostly I saw bad. I'm sorry but I'm going to give you my honest opinion here. I'll review you as a 3d artist perspective because I've done a little animating (mostly modeling).
Your animation was... terrible at times. Max has a walking and running with the nice foot step animation settings. I realize animating in max can be a tedious thing but alot more effort could of gone into your frames. I felt it was rather lacking though.
Your lighting was good, I felt you did fine with that.
Your modeling and texturing was very simple. You could of modeled more detail and textured more precise but I suppose that wasn't the effect you were trying to achieve with this animation. Texturing is a pain and runs up the render time so I realize you might have kept it simple for the sake of rendering. All together some of your models looked imported (aka the gun and maybe the airplane) the human characters were iffy. You did fine other then that I suppose.
The animation in a whole was thought out and the use of camera was good. The idea of the animation was conveyed. Pixar quality is a pain to achieve and just all around long to render. I know from the past that making a 3 second animation took me over 3 hours to set up and render. To comlplete a full animation takes a long time as you stated. So I congratulate you on your award and hope to see something again from you. Don't take anything I said personally because I hope to see more of this on newgrounds. Maybe even get a section on the sight for 3d eh?
Good luck.
