It's impressive sprites...
The sprites look custom made, and they are well done. I'm very impressed with those. the flash animatin on the other hand is a little bit choppy. Your backgrounds jump as they move, which is an eye sore... you may want to either increase the frame rate, or slow speed up how fast they move... something to make it not appear jerked and rushed.
Also you have prolonged pause in one section which is ok for dialouge moments, but the sprites should move a little just to keep the visuals from getting stale.
Those are my suggestions and I will definitely be on the watch for your upcoming flash movies.
