When placing and naming civilization markers on a map, we can follow some basic rules.
Where rivers reach the coast, there will typically be at least some amount of tidal estuary and delta, so the coast should angle in a little there; unlike most bays, these will be sharp rather than rounded. Urbintor is a good example.
Humans live on the water, and on trade routes, so the first (and probably oldest) cities should go anywhere a river joins the sea, like Markal, Porlat, Kesidi, Mestas, and Urbintor again - great trade and fishing.
River forks are also good places for trade and water, too, as well as being nicely defensible, protected on two sides by a natural "moat": in this map, this seems to be one of the main reasons for placing cities.
There's a great sheltered bay with two rivers leading from it, leading to Bloodhill and Latale. This bay would normally become a huge city pretty fast, unless there's a good reason for it not to. Probably the biggest in that continent.
Bays are caused by erosion from the sea, so will typically be rounded (no examples on this map), rather than pointy (Distad, Dalere, Vantia City, Turrum, Minra, Dongan, Montibem, Pordeut, Todora, Estreor, Porlaba, Eastport...), unless they are fjords between two mountain ranges. Fjords will typically end in at least a short river.
Names mean things, and those things get used in multiple other names: in Pordeut, Porlaba, Porlat - I'd suspect that the "por" is a degradation of "port", and "lat" has some meaning, as it's also seen in Latale.
Eastport shows the word non-degraded, showing regional differences, which is nice. The same region (Kingsland) has BloodHill - that region seems defined by readable Englishy names. My suspicion is that this will be where the heroes will start out, and venture into more foreign-sounding places. A bit tropey, if so, but not a terrible thing.
Outside of that southern continent, though, names seem like just 2-3 random-syllable things, with no clear sign of meaning. Having several river-fork cities have a similar prefix or suffix (-ford, -bridge), and so on, will add verisimilitude: see https://en.wikipedia.org/wiki/List_of_generic_forms_in_place_names_in_the_United_Kingdom_and_Ireland but obviously, like your "por-", make them regionalized to the tongues of your world, rather than using them directly.
As a counterpoint to that, for a fiction writer, having names which are easily confused by the reader (bannockburn, bannockbridge) is usually a bad thing. I'd go with having the first syllable unique in each case, and shared suffixes, unless the point is to show the two places are very close together (bannockburn being just upriver from bannockbridge, perhaps).
As well as rivers, other trade routes matter - places where major roads join, mountain passes, etc. Also significant sources of resources, like mining town, fishing villages (the whole coast would normally be populated with these before inland areas got many towns), etc.
I like the placement of Erten & Estreor, placed to take advantage of the trade that flows down that channel from Gahotere and the Vanlian empire, to Kingsland and southern Aumedeszel.
