The curvature of the roads is odd. If they were running along the easiest route to build with the contours of the land, they'd twist around more. If they were built to be efficient and engineered for speed, they'd go straight. What you have there looks more like a mathematician's graph than a road system. Maybe if non-humans were building the roads, they'd have a reason to do that, but the human preference is generally to go straight if possible (shortest road).

I actually think the mountains and forests are okay, although I would maybe want to see the mountains made darker or colored a little to make them stand out a bit more. You might want to put some foothills along one side of the mountains.

A compass rose would be a nice addition, but a scale is probably more useful. I'm not sure what scale this is actually supposed to be. Is this a continent or an island cluster?
