Hmm...
I havn't seen any of your previous flashes, but the animation looks fluid enough to me. So I think your goal has been achieved if it makes you happy. One thing that bothered me though, was why did the Blue guy have his "Instant Nun-chucks" and then just stuff it in his belt again! (or what looked like he was stuffing into his crotch.) I can understand the guy being overconfidently powerful and all, but that just makes him pulling out his "Instant Nun-chucks" completely unnecessary and makes him look really stupid. Another thing, were the sunglasses at the very end all that necessary? And couldn't you have a scenery in the background, and have a side view for the character that way it's easier for the viewer to identify that "The main character is running away from the compound before it explodes" All in all this is an "okay" flash, and I think your goal has been achieved with the fluid motion, so good job on that. I give you a 6, and Peace Out.
