Very wonderful river "snaking" through this valley. I like the lower portion of this scene the best. The forest has very good detail and you didn't lose detail in that area (or any area). That said, the forest is pretty dark relative to the foreground and sky. The mountains and snow are just fine, but somewhat too center-middle to be harmoniously composed. I assume the sky was overcast with some midlevel cloud detail. That would explain why you left the sky somwhat light gray tone. If the sky had blue, you could have shifted around the tones of this entire landscape (lighter trees, darker sky and more detailed clouds).
