Looks cool. Scene could be a bit bigger, so we can see some more details. Needs some light effects on the light balls. Also some light effects on the gun too. Should see some light on the ground and in the area from the balls of energy. Whats the "Us vs them" project? There was a game called "Dark Colony". It was a rts(real time stratagy) game featuring humans vs greys battling for the control of Mars.
