From what I know 4 city NC before turn 100 is considered ok so by that standard you're there. Too bad on missing out the religion. I haven't played the map but from what I can tell getting one could have been achievable - that's a faith natural wonder in Samoa if I'm not mistaken. I think the empire could become more compact so that it's easier to defend all cities in case of an attack from multiple fronts. What I would have done is get 2 more mountain cities (with Tonga 1 hex to the right to make room on the deer near mountain, and one more city above it.).
Needless to say, there is no single "one way" to play, so this is just my opinion, in a coastal zone with mountains, I, for one, would have made as many mountain cities as there's room for, and then feed capital with food while setting capital near mountain too. For this probably full liberty followed by full tradition with getting Temple of Artemis asap. Getting only 4 cities but with all near mountains seems just as powerful, going for fast Astronomy to take advantage of the observatories. (possibly waiting to steal it and teching fast Acoustics for Sistine Chapel to try to get the suggested win condition.
