Okay I feel like a piece of shit because this is something you're obviously passionate about and everyone makes maps like this when they first started (including me!) and so uh let me give you a few pointers:
Get Paint.NET. It's old as shit and so will run on just about anything and will allow you to have pretty text without the artefacts that regular MS Paint will. It'll also give you access to layers which once you get used to are a
game changer when it comes to maps.
The geography itself, while viscerally phallic, also is kind of untextured. Like, there are no islands (and that doesn't mean just add one island add a few small ones, see: the Canadian Sheild or Zanzibar). It being connected to a continent is fine but the way it is is kind of abrupt. The line is so smooth it looks artificial which is in opposition to IRL borders which follow mountains or rivers.

There's several small islands, points of interest, varied geography. I'm not saying copy this, but there's some traits that are also kinda useful. Maybe go on Google Maps or Google Earth and look at
road maps of places that Pokemon regions are based off of.
Or even compare to the Caspian sea which is the region I think your area looks the most similar to

Notice how all of the borders with the ocean are sorta "lumpy" and have a lot of texture.
Otherwise, I dig the names actually. "Vikland" seems like a solid pick for a "Pokemon-ified" Scandinavian area. It's been a while since I played a Pokemon game but iirc they have a lot of other small towns and cities. Maybe you could make a map where you highlighted the major cities that have gyms or the Elite 4 and then others that have smaller settlements. Maybe even add coloured sections that designate what type of pokemon can be caught there?
This five year old what the fuck tutorial I made on WorldA maps is not immediately helpful but many of the concepts I discuss are pretty useful.
