I have a couple of comments after looking at the save.
.) First, the capital needs one of Edrine's workers, otherwise it will work unimproved tiles soon. It also needs a lighthouse to improve the seafood.
.) Edrine stagnates while high food tiles are possible and the cat would still be built in 3, this should be changed immediately.
(I built the granary because the city grows really slow)
.) Bursa (nearly) stagnates too and is building science. I can only guess that this was meant to be a placeholder and
a temple was intended next turn when the religion will spread, otherwise I would have to use

Seriously, as I stated some posts ago our main concern is happiness. Therefore, specialized low-shield cities like Bursa (and Commerce cities
like Konya) should only build happy-buildings and commerce enhancing ones (prefferable science-buildings)
I see the point that a temple is not available until next turn but in that case shields should have been invested towards colosseum
or market. Hammers invested in buildings decay only after a long time (IIRC 50 turns, while the ones for units decay rather quickly)
so it is no problem to half-finish a col. or a market, then switch to temple and finish the former afterwards (in case of col. it is actually
pointless as it costs the same amount of hammers than the temple)
This is a strategy one should keep in mind when developing a city.
Additional, growth in cities should be timed with the future happy limits, not with the actual ones.
Next thing, Bursa has already enough farms to support at least 4 scientists, so a switch to caste system is necessary.
Whenever we hit happy limits in our specialized cities (Bursa and New Dehli), we should max the amount of specialists.
Good work on getting the army started, we should conquer Ghandi soon.
When we get this second specialized city to work with a lot of merchants, our maintenance problem will be gone and science should
be up 80,90%. (Ultimate goal would be 100% scienece and one (or 2) wealth cities with tons of merchants.
Tech: Philo would obviously be nice as more religions would open up the free-religion option if we have to use it for diplo at some point.
I made an updated dot-map.
The beaver colony in the north-east is important, the markets will double their value (and those of ivory)
In the south, the warrior is just clearing fog to prevent barbs from showing up, I would go with the original site
and settle another commerce city later on the island (both are close to the capital which reduces maintenance).
