I was considering doing one or both of the following as well:
1) Adding some more forested areas
2) Redoing the mountain at the middle to stretch it out a bit. I'm thinking of bringing it out to butt up against the hill to the southwest and stretching it to the northeast a bit. I could probably just add some mountain in layers beneath the current mountain, so I didn't have to give up my terrain features and rivulets coming off the current crags in the mountain.
Looking for opinions, though I'll ultimately make up my own mind, of course.
