Oh My, this is beautiful!! I love the compositon, reflections and colours :o) Only thing I am not too sure about is the loss of detail in certain parts of the mountains (glaciers?) where they meet the water. Still, not a scene I get to see very often! :o)
What a lovely location and composition thereof. Looking at the picture I am asking myself what is lacking, something is, and yet I can not put my finger on it. As this is such an interesting and potentially gorgeous landscape, I would think that a deeper blue and a slightly higher curve/black/contrast could make a difference. have you ever played with the LAB colorspace? Check 'Photoshop LAB Color' by Margulis out. It is worth it. Difficult but very valuable.
Love the composition, the two dark area's sloping inwards bringing the eye to the view of the mountains nicely.
I feel this would look good in black and white.
