Nginx + Wordpress caching - Configuration file sequencing

Question

I'm new to Nginx and Wordpress as a combo. I would love a sanity check on this server side caching code.

Specifically

Is the sequencing correct - esp. the location statements?
Is there anything redundant or critically missing?
If I wanted to set a different cache time for say .mp4 and png - eg 1d, not 1w, how would I do so?

Many thanks for your help.
