Louis XXIV
Le Roi Soleil

Where are you sending your cargo ships? They appear to be internal? Send them to City-States. If you can't reach them, disband your cargo ships and build caravans to do the same.
Remove the road between Mosan Kahni and Rio (and the random gibrish roads near Rio). You want one road path, not alternative paths. Those cities are all so small that it's worth just not connecting a couple, but they can be built along the way, so that's not the end of the world. You just need more money. If you were going Tradition (guessing based on you suggesting you have Oligarchy), get Monarchy.
That's all I can think of for now.
