Well...
It's an alright start for ya. It's not exactly something i would blam, because of obvious effort and time put in. Then again, its not really the best thing in the world now is it?
you seem to have a good grasp on liniar objects: ie, guns, inanimate objects, cars, planes, ect. i liked the reactions of the streaks on the road, well done. however your organic animation is very much lacking. as are your audio skills.
stay away from the stick men, the filled in black characters, and work on more of a story, tell us why the hell they shoot this guy in the begining. hope this was helpful. and if you want any pointers on how to do something in flash in the future feel free to contact me.
Rock Rock on!
