Make it yours

Eight seconds is enough for one pass; for 5 seconds say the bridge is already half-built when the shot starts.
Change 'camera flies parallel' to 'drone shot from behind the first habitat' for a version that shows the bridge approaching the far cliff.
Keep the 'Sound:' label and the two sound items; the chatter is what makes the swarm feel active rather than silent.
