I love the general layout of the map - the areas are distinct and feel natural, there many interesting places and none feels out of place. I can picture many adventures taking place here. I'd travel here any time!
I like your style as well. But besides the contrast there is the issue of semi-transparent mountains (see Mt. Ary'At). Also I suggest (with the little expertise I got) a smaller sice for the trees, and maybe more different trees of the same sort.

But since you made this map before joining, you'll certainly work wonders from here on.
