I have a D7100 also with several zooms
My primes, all Nikon, are 35mm 1.8, 50 mm 1.8, and 40mm macro, I think is 2.8.
I am saving up for a wide angle prime.
I can carry all in my vest and focus by walking more.
These three use 52mm filters so save money on nsd and polarizing.
I still do nature landscapes but have added city and architecture, inside and outside.
Doing interior shots is a good reason for getting a "wide" prime, But your current set sounds like a nice "walking around" kit!
