*UPDATED, SEE LAST POST*
The Pineta valley is located in the Pyrénées Mountains, in Spain. At the begining is located Bielsa, to where I went 2 times since it is the exit of the tunnel from France. The snowed moutain at the end of this 12 kms long valley is the "Monte Perdido", which means "Lost mountain".

A higher atmosphere setting would help this image. Everything else is great. Nice scale for the trees.

What do you mean by "a higher atmosphere setting"? I don't see much noise...

I found when using the free version of Terragen 2, that increasing the atmosphere sampling helps add some 'crispness' to an image. It seemed to me to make the colors more vibrant. It does add the render time, I know. But when you only have an AA of 3, every bit helps.
It shouldn't really have much effect no color at all, except in very specific circumstances - it basically effects noise. Have you done empirical testing of this?

Almost all of the images done on my Flickr photostream use high atmosphere settings. Schmeerlap suggested increasing the atmosphere samples to me some time ago. It does work for noise, but I believe it helps with lighting. Better light always makes a better quality image.
It helps make those godrays possible without adding raytraced shadows to the clouds as well.
njeneb, could you post 2 images to compare?One with default settings, the other with higher atmosphere settings?

It will be a couple days. I just got off a sixteen hour shift. Maybe 11/25, Wednesday?

Thats pretty epic.
nice update! The trees look a bit to sharp for my taste.
Awesome sense of scale! Although I do agree with Walli that the trees are a big sharp.
I think using a different image AA filter would help now. I have Blender rendering barns now, but one of the selections in the extras tab of the render settings has a soft filter.
Trees sharpness must come from post-processing (Photoshop: accentuation 100%, 1 pixel, 0 levels).

Sometimes post processing can do more harm than good. I like the direct render much better.
If I may share some advice: look at the tree distribution, its not natural in two regards. For one, it's not dense enough. It needs to be much denser. Secondly, the distribution is too even. I suggest to use a powerfractal or cloud fractal shader as a distribution shader, and experiement with that a lot to figure out a natural distribution.
Other than that I must say that the scales and colors are chosen well, and the image could certainly develop from this good start.
I'm already using a distribution shader to limit the slope,so how should I add the powerfractal?

just add a powerfractal as the blendshader for the distribution shader.
