Nice improvements here!
About contrast : I'd work on colors before adjusting any contrast (which doesn't make that much sense on your map with only a few color touch). It seems that you choose to color the map with some kind of brights colors (looking at the sea) so I'd go coloring the other areas of the map (lands, moutains, places of interest and so.)
I'd also get rid of the farms that looks too computer generated imho. I saw you want to steal my Green Havens one Go go go if you feel it fits your map!
Also I concur on forests, you should make then more dense in my opinion.
Btw good job overall
