I like the style of the map! It has flavour!
That said
- I'd move the Compass to the map per se, instead of inside the legend
- Same for the Scale, also move the numbers of the scale to match the slash divisions instead of centered for each slash...it's confusing to know where the distance actually is 400, 600...and also...400 what? 600 what?
- The river on the east, around Tauriana, seems weird to me...might just be me
- I might be wrong but the mountains formation in the east seem wrong from a tectonics pov. "Thousand Rocks" and "East Guard" go opposite directions which afaik would be impossible.
I'm not an expert, so take my advice with a grain of salt ^_^
