As always, you comments have helped me develop my maps (and skills).
It was also my thought that the map was too bright but I had no idea on how to darken it, as I almost exclusively use CC3 it was difficult to filter etc.
Ravells comments set me off to find out what desaturate meant in mapping termswith the final conclusion that maybe I need to invest in photoshop.
I sort of got round the problem by adding a grey layer which I then made transparent and blurred. I then finished the whole lot of with a touch of Spatial Matrix Processing to darken the map. I have also added a black blur to the river to make it stand out a bit more.
I think this is a far as Highmoon will go for now, I keep fidlding and its time to move on, as indeed have my players!
