Great shot. The dynamic range and color range are very good. Tonal quality is low, but that is due to the high dynamic range. Catching some sun rays is really fortunate.
Minor Suggestions:
One thing to be careful of is the Blowout in the sky. It is not much in this case, but much more and the photo cannot be used commercially. Repairs are possible, but not easy, and many times not practical. Blowout can happen when dynamic range is increased in post processing. If so, you can select the highlight areas in danger of blowout, give it a large feather, invert and hide the selection, and then adjust dynamic range, but watching for banding in the selection zone.
Did you take this shot using HDRI? This is usually a good way to preserve fine detail and still maintain hight dynamic range.
If the blowout happened in the original shot, you can try taking the shot in "Histogram" mode, where you will see if and where blowout and burnout will happen.
Another really good option is to use a "Graduated Neutral Density Lens Filter, 0.06 Hard" in this case.

this is.. wow! what an useful comment! thanks a lot for the many suggestions! that was only an experiment with hdr but I don't like particularly this technique.. I processed this shot using photomatix.. yes I took the shot using the hystogram mode trying to make the exposure to avoid blowouts, but there was too much difference between the highlights and the shadows.. I will try the filter anyway! thanks a lot again! please take a look to this [link] this isn't an hdr and I like it much more!

You are most welcome. The link you gave me has a problem, it says the file does not exist.
HDRI can really help improve shots, but most photographers push the parameters to make it very dramatic. You can make the HDRI effect more subtle.
When you try to increase dynamic range in a regular photograph, it is at the cost of image detail and tonal quality. If a Grayscale image starts with a full 256 tones (black, white, and shades of gray), and then you increase dynamic range sharply, you might loose over half of the tones. It may look crisper, but also rougher, and you loose fine detail, with highlights going toward blowout and shadows toward burnout.
HDRI allows you to increase Dynamic Range without loosing tonal quality and fine details, ASSUMING that you do not push the parameters and add much tone mapping.
Before giving up on HDRI, it might deserve more experimenting. Even some Portrait Photographers are using it in a very subtle way.
-----------------------
NEUTRAL DENSITY FILTERS or ND filters are "grey" filters. An ideal neutral density filter reduces light of all wavelengths or colors equally. The purpose of standard photographic neutral density filters is to allow the photographer greater flexibility to change the aperture or exposure time, allowing for more control, particularly in extreme circumstances.
A Neutral Density Filter can be used to prevent blowout when photographing the sky. In an another example, on a very bright day, one might wish to photograph a waterfall at a slow shutter speed to create a deliberate motion blur effect. In order to do this, one would need a shutter speed on the order of tenths of a second. There might be so much light that even at minimum film speed and a minimum aperture such as f/32, the corresponding shutter speed would still be too fast. In this situation, by applying an appropriate neutral density filter one or more stops can be taken out of the exposure, allowing a slow shutter speed and more pleasing effect.
GRADUATED NEUTRAL DENSITY FILTERS are especially handy for shooting from shadow to sky, where you would normally blow-out your sky, and for shooting Sunsets. You can get some very good skies and sunsets that way.
In short, the filter is clear on the bottom, gradually increasing near the center to transition to the filtered part of the lens in the upper half. This way the sky can be filters, while the rest of the image remains unfiltered.
SEE THIS: ND filter on Flickr - Photo Sharing! [link] for a good picture.
Filters can be screwed into the lenses of most SRL cameras (screw in filters), or you can get drop-in holders for the lens, or you can simply hand-hold one in front of the lens (not very convenient.
If you're on a budget and can only afford one neutral density grad, the most useful will be a 0.6 Hard Grad. A 0.6 Soft Grad gives a smoother, more gradual or "soft" transition from clear to filtered, while Hard Grad gives a fairly abrupt or "hard" transition from clear to filtered. The Hard filter is better when you go to longer focal lengths.

Filters can be screwed into the lens of most SRL cameras (screw in filters)
For lenses that you cannot screw a filter into, there are 4 systems available (drop in filters). Here is an excellent illustration of them (about half way down page): Filters Buying Guide: Manufacturers - B+W, Cokin, Lee Filters, Hoya, and Tiffen - Vistek Pro-Camera and Video Store
[link] Additionally you can simply HOLD a filter in front of your camera lens with your hand (not very easy to do without getting the filter smudged). They come in sizes like 3"x 3" and 3" x 4".

yes è un esperimento di hdr, secondo me non riuscito.. non mi piacciono gli hdr, troppo artificiosi.. devo dire che con la pellicola, che indubbiamente ha una latitudine di posa maggiore delle digitali, non ho avuto mai problemi in quanto in linea di massima prendevo sufficiente dettaglio anche sulle nuvole e sul cielo.. poi con questo digitale e con le diavolerie software come gli hdr si può fare tutto.. però io non sono molto bravo a fare queste cose, come puoi vedere da questo irrealissimo paesaggio. però è proprio un bel posto!
