As for advice i'd say work on your pacing. Trailers are supposed to be short and snappy. Watch a trailer for an action film and look at how long each shot is and then compare that to the length of shots in your animation.
On a more techinical note, try adding a preoloader to your animations as this allows the whole animation to load before being played and prevents buffering that might make people down-vote your animations.
