I love the quiet light. My favorite time of day is the quiet light just before a sunrise or just after a sunset. The blue/orange combo works really well here. The colors are pleasing. I'm glad to see the colors subdued a bit (you could easily go too far with saturation on an image like this).
To my eye, there's just a bit too much negative space at the top and bottom of the frame. The horizontal layers of the water, mountains, and sky are great, but there's just not enough interest at the very top and bottom. I might try cropping slightly to get a "fat" panoramic (i.e. something at a 1:2 ratio perhaps).
