Maybe a bit. I am not sure of the game settings, in that I see the VP monolith and I see a box for locked alliances. I am not sure what those are about.
If I ignore that and just go on the basis of a normal epic game, I would say some things need to be reevaluated.
Niagra making an archer with no barracks and it already has two units. A worker doing something, but no workers in other cities. With a size one, it does not need two workers, one should be connecting other towns and one should be improving tiles in the capitol.
I would probably switch to a barracks and use them to chop and get it done fast. Since they are already here.
I am an unfriendly guy when it comes to AI troops next to my capitol. I would switch to a spear or archer. Then a worker and then we will see. If the archer does not attack you, you can make an archer and force him to leave.
If he does, you may be alright as the river will help the warrior. I would not have waited till the archer was next to my cap to take action.
I am not going to start a granary in Grand River as it has no forest to speed the build and no workers to build mines and it has 26 more turns to go. You cannot wait that long. I would pop a worker and then figure out what to do. I have no idea of what has come to pass, so it is no clear if I need to gear up for trouble, but it looks like it.
Not much sense in irrigating those plains, if no one is going to be working it for a long time. Those worker turns could have connected a town or made a mine.
I would not have a worker on a hill working a gold deposit so early in the game. It takes too long to road and mine a hill. You are losing money form lack of roads and shields from lack of mines and you want to be connect so that fur will help all towns and they can benefit from the capitol.
