As mentioned tech wise you are relatively good, but there still is a lot of mistakes and you got away nicely only because it's Warlord diff. So that's why you are here and I will try my best to move you a bit forward.
OK.
Biggest problem - number of cities. 7 is not enough except for situations where you aim for cultural victory and I think that is not the case here.
City specialization, it seems to me that everything is just commerce. i dont see any sort of GP farm/prod city, you should have at least 1 from those kinds given such low number of cities.
Civics - to some degree US gives you good since you almost everywhere have towns. But you should then take the Free speech too. Why are you not in FM? being in Theocracy brings you nothing since you build units in 1 city, everywhere else you build buildings.
I switched to Rep (that one is questionable, US isnt that bad in your sit, but it gives happy), FS, FM, OR, Caste (that is neutral since it allows specs that is nice synergy with rep, but you dont have gp farm to really abuse this) and am sitting at 500 bpt
Land - not enough workers, corn unimproved, should be first thing improved?
City settling - i wouldnt settle knossos the way you did expecially when the fish is locked by dutches. Remember food is top priority and you killed the only food that city will ever have. settling 1E would be better.
Scouting - you dont know enough about world. You can buy some world maps around from AIs after paper...
Victory - at first sight one would say that you are in good position for diplo victory, but at the second sight you will realise that you are not. I dont know if you use BUG mod, but there is in diplomacy advisor screen called "glance" and it shows you which AI is with what AI friendly/pleased etc and more important the correct number as calculated from mouseovering them in relationship.
You would realise that Gilga is more good on the way to diplo victory and he is top leader in pop, so he will probably be in voting after UN.
I think you should get more land. get some troops asap and use your tech lead. i see you didnt tech for cavalries, so you will have to go with rifles+cannons
Buildings in cities - I just realized that you are kind of builder ;-). You have streamline a bit specialization. Btw in cap you shouldnt have moai as second Nat. wonder but Oxford uni, it gives +100% research multiplier.
I hope next game goes better! Oh and read some strategy articles about city spec, sisutils beginners guide. I will allow you dominate on noble in quick time.
