few mistakes with the territories border i saw in two main places. They dont quite seem to reach the edge of the border.
Whereas one line goes over
probably more, i will keep a eye open for more.
The coloured glow looks slight pixelated
could you maybe add some different terrain, maybe some lovely cliffs, maybe the top left castle could have some cliffs around to reduce the ease of attacking the villages.
the darker legend, it is alright, could you try and make the font look engraved, would could make the engraving lighter than the wood.
