Valley, with and without

The highlights on the water are sublime

Fantastic river and the wall textures and colouring are really nice too.  I think you need a couple more pine tree models mixed in up top though.  That particular tree seems to have a fairly distinctive top bit.  Perhaps having a dead one that had fallen from the cliff somewhere in the river would be a nice detail as well.

Looks great Ulco.
Maybe just some other interesting displacements on the rock walls and a little variation on the river side rocks?
There is a nice photo look in general.

I'll do some more work on it. Despite the long render time for the water (even without transparency), it may be worth it. May do crops without water and just comp together... I have to be careful what trees to choose, you're right.

Next iteration. Interestingly this rendered faster in 2 crops than it would have as a whole, as if remembering hampers the speed. Hope to get a waterfall in and some more interesting cliffs...

It is looking more and more impressive, it must be a lot of works !

It's not too bad.

@ David: You can make a flattish sloping terrain first, add your river by mask and work on the outsides with rougher displacements from there. If that's what you mean by making a soft slope for a river.

It's getting better and better... I really have to get to grips with using functions
