Thanks you for the nice comments, gentlemen

Doug, there is a little secret, a simple action that instantly adds a lot of depth to any of your shots: the visibility in the weather settings.
In my shot, I went to the advanced weather settings, and I set two distinct things:
- for the clouds, I created a layer of Cirrus clouds at high altitude (like, 30.000 feet or something like that). Ok, these are not so visible in my shot, but daytime, they really make a difference. Of course, I have installed the HDE Cumulus and Cirrus textures in my FSX, they work well (but the rest of the package does NOT work) and they look just amazing.
- for the visibility, I created a visibility layer from the ground to 10.000 feet, set to 60 kms more or less (I don't remember the exact numbers). Instantly, the background scenery appears much more realistic. Some haze appears between the distant mountains, and they give you this feeling of volume, of distance, that is completely missing in pure clear weather.
Finally, I set the flight time to dawn. There, the magic lighting happens
