Most important is: does it make sense like this?
Or is it confusing?
There are some rules that help keeping a sense of direction (180-rule in conversations or duels).
Some rules for compositions that help to keep it 'in balance' (like the rule of thirds).
And there is one (secret) rule, almost nobody mentions:
'edit evokes thoughts', meaning that the previous shot gives context to the next. It helps to give meaning.
But don't overthink this now.
You just need to get in action. Being 25 years in only a setback if spend the next 30 years pondering about what shot to shoot instead of actually shooting.
And a very important rule:
Sound is half the experience.
Some other ITers can word that much better than me 
But don't let less than optimal sound stop you now.
