First, welcome to the Guild!

Second, river issues aside, I really like your hand-drawn stuff.

Third, with your new computer-assisted revision, there's a couple of things you might want to consider:
-The land seems to float over the ocean due to the cloud effect you've gone with. You may want to add some darker blue around the coastlines to help ground things.
-I'd enlarge your canvas a bit so everything doesn't look so crammed in there. I like the general shapes and layouts you've got, but you need more room around them to let them breathe.

On the positive side, the mountains look very nice, and the overall color scheme you've got looks great. Keep up the good work!
