Three cheers for finishing things
It can be tough when things are less than satisfying - I know this well.
Sometimes it finishes well and sometimes just meh.
I think this came out well. It has a nice mood and atmosphere.
I particularly like that you have the nice shadows for all the trees.
Also like the mood lighting on some of the mountains. [some seem lit more than other areas]
The coastlines look good. Maybe some more lower foothills leading up to large mountain ranges next time.
Border and legend look good.
For curved text - I would just go with a gentle U curve.
I've tried multicurve paths before and they usually don't work so well.
I think it works all-in-all though.
