It is good Andreas but by doing it that way you don't get the full range of colours in the rocks. I think it is a lovely shot but for me the combination of textures and tones in the rocks combining with the grasses is what makes it. If I postworking it more I would probaly try to get a bit more texture and warmth into the grasses. My sugestion is if you want to go with the colour version is you balance the colour first, then do any adjustments to saturation or tinting you want. I balanced the colour with levels. It is common to get a blueish cast with this type of shot especially if you use a polarising filter which tends to cool colours as well.

And every one said, 'If we only live,
We too will go to sea in a Sieve,---
To the hills of the Chankly Bore!'
Far and few, far and few, Are the lands where the Jumblies live;
Their heads are green, and their hands are blue, And they went to sea in a Sieve.
