two artists
To me this flash looked like there was two different artists involved. One of them was good and one bad. The good bits to me were some of the faster moving tunnel bits and the distant shot of an army jumping across the buildings. There were howerver a couple of bits that threw the animation timing a bit. The slow bit where he jumps on top of everyone and just after that I think there was another slow bit.The explosive bits could have been stylized better.
Take the good bits and dump the bad and youll have an excellent flash.
