Hmm...
You've certainly gotten better since last time I've seen you, but even so, the battlefield idea has been done to death. It was painfully unoriginal..
Excluding that fact, the animation was a step up from before, the blood particle effects were pretty nice as well as the stage destruction. The tank and helicopter looked pretty nice as did the explosion effects. I like that unlike most brush animators you have a fine mix of movement and effects which really makes it more outstanding than your typical brush animation. I can tell that you've put a lot of time and effort into this so keep it up!
Next time come up with something a little more original man!
