This light is wonderful. I like the river too. It would be good if you could eliminate that one cloud on the right, which looks like it's cut off at the top. You could try by masking it out by a simple shape in that location, you'd have to manouver a bit to find the exact spot.
And the trees bug me, the firs almost look like shadows from the other trees. I think you should use only (more species of) deciduous trees, no pines, firs or so. If you do, locate them at higher altitudes.
