Hmm... I don't know if the numbers are definitive, but if they are you should maybe do something as many of them are going out of their banner : 22, 15, 38, etc...
It's certainely a matter of taste, and because I loved so much the 'just orange' colors harmony of the map before vegetation, but I would use a different green, less saturated, for the trees (but it's maybe just me, because I always have problems with green). However, the shadows are great !
Maybe find (or paint) a less repetitive texture for the big banner on the top left ?
