This looks good. A few comments:
1) some AI are still missing cheap techs (Poly, Priesthood) these should be sold, getting you some money. Since the value of these trades is relatively low the happiness hit from trading with worst enemies will not be too bad. Right now you could easily make 260

.
2) All your idle cities are producing science. Since modifiers do not act on direct production in most cases it is better to produce the yield where the average modifier in your empire is lower. Usually that means you want to build Wealth, not Science.
3) Pusan is getting culturally pressured by Charly. To avoid the city flipping some parts of your army should be placed there, and not at the border near Monty. (Since you are Creative and that looks to be a city that has only expanded borders into the third ring, you might be OK soon, but best not push your luck.)
4) Granaries should be whipped, especially in high-food, low-production cites like Wonsan.
5) Why are you spreading irrigation to Cheju? There are no resources and AFAIK this does not give the fresh water bonus.
6) This is more contentious, but I believe that you do not have very good odds to get the Mausoleum, building it is probably better than building Wealth, but currently your biggest priority is probably spreading the religion, and your capital is one of only few cities with that religion. It should probably be building missionaries. Only Angkor Wat is very slow.
7) The cities on the Islands should be up ASAP, since even without the GLH they have seafood and two trade routes, meaning they probably pay for themself even at size 1, thus 1-2 Galleys and 2 Settlers should be built/whipped.
