I like the two ridges you've put in, there's a sense of the land rising towards the north. I'm not sure that they benefit from being attached to the lines that delineate the peaks of the mountains though. I think the second (more northerly) ridge is most successful. Part of that is the angle of it as well, but I especially like the way the river cuts into the ridge and disappears for a moment.

This looks like it's going to be another impressive map!
