On one hand, I feel like this would be more powerful as a black and white. On the other hand, then you'd lose that beautiful green-brown gradient on the landmass. Either way... it's a lovely work. My only -real- nitpick is that the top of the mountain-thing is a little bit over-sharpened.
This is an absolute "wow" factor. One of the best scenery photos I have ever seen. Perfect simple composition, amazing lighting, beautiful soft colours. The depth of field is amazing. And the additional dividing line of water makes the focus point stand out even more. The texture of the grass, the clouds going out from the mountain top - it is all like a painted picture. It evokes so many feelings.
