An F6 screenshot of the tech tree would be handy. Is there possibly another tech that we might want to get before Communism? For example, something like Physics/Economics or whatever their equivalents are for a free Great Person?
Settling on top of Oil does mean that we can't disconnect it later if Unhealthiness from Factories is becoming an issue. Is that location really the best that there is?
Are we attacking anyone or just building up our forces? If just building up, where should the troops go?
What types of promotions? Combat I and Pinch for Gunpowder units, then City Raider for Cannons?
If Jacksonville needs to build a Library, should we aim to hire 2 Scientists there once the Library has been completed? (I don't know if that situation will happen in this turnset or not.)
Settling on top of a Cow? I hope that it's a Grassland Cow, so that we at least get +1 Food in the City's Centre. If it's a Plains Cow, that's a pure loss of the Cow. If it is a Plains Cow, is there nowhere else to settle the City or are we gaining an otherwise-unworkable Seafood Resource out of the deal (in which case it's reasonably justifiable)?
