Well, that is a relly nice picture; but there are a few things that I have to mention.
The location is really beautiful, but to really get it to work you need to pick the right moment for a picture. You can see the sun starting to touch the hills, and I don't know if you really wanted that - but it would have been better if you wait until the sun is above you, or at least that much that there are no shadows.
This picture screams for brightness, and sadly the clouds are a bit in the way too.
I don't say it is a bad photograph, but you sure have much more to offer.
I don't agree with the critique at all. I clicked "unfair." This is a wonderful photo. Just the right amount of "brightness" and shadow (in my opinion.) The clouds are "in the way?" the reflection of the clouds is a lot of what makes this a beautiful shot.
