Huge miss on 15th, believe there is something weird with the vegetation there as it suddenly gets very dense between the marshes..? Also, indistinct marshes are almost invisible, and the course missed rc-legs.
I don't know about those marshes man...
Jokes aside, here's some thoughts:
The colours you use makes the terrain feel a bit cartoonish. Water in Scandinavia is not very blue, rather it's more towards brown.
And the ground is not covered with those leaf-plants, and marshes are not covered with ivy and ferns. What would revolutionise the look of these maps would be if we could edit the ground-covers so that we could make e.g. blueberry bushes and heather (that does not affect the runability).
