So im thinking;
Gardening: Foggy hazy morning, someone is gardening (camera starts low and slowly goes up, eventually focus pulls to behind the gardener, where a construction van/truck is going to its job.
construction: follow the truck to the job location, start completing the job, maybe we have a argument with a construction worker and a miner, this takes us to mining pov.
mining: shots of the job in hand then we take the miner to get some food at the uwu cafe, they bump into the police dept
and so on i think having a lot of things show a connection can help the audience follow along so much easier. the towards the midway point we change the tone, darker music more crim/pd side of things. mixed with ems etc. the follow up towards the end with the doj gavel.
mechanics: show some cars being worked on, before and after etc. mechanic talking to customers.
eMS:shots of a surgery, ambos on scene, interaction with various different people. etc
