Nice rhythm overall and your sketchy red-on-black art style is appropriate if a little unrefined. You could probably benefit from making a strong storyboard or outline before even opening Flash and trying to stick to it as much as possible. Also watch your musical transitions, they're a bit jarring. I liked the part where he flipped backwards over the cop car and shot through the windshield in slow-motion, very imaginative! I was sad to see the bike (R6?) get trashed, though.
You have talent. You should keep refining it.
