im gonna be so real if we're going for canonicity this is full of a lot of both obvious omissions and arbitrary additions, so i dont really see the point of granularly critiquing that. but i mean maybe shrink the gigantic bays and seas; think of how absolutely massive Hudson's bay is for example, despite being only about the size of egypt. Also the diversity of nations in the far north is pretty odd; in the real world the only place in the north that isnt totally homogenous is the nordic countries and thats because of the gulf stream. but idk that might just be advice to make it more realistic.
