Redko,
Great textures... but your send is "too white".
There should be a small drop of brown in your desert color. Most of your pictures are lighter than satelite image of Lybia (south of Tobruk)
...and all desert paints on aircraft are "much browner" than your desert. Just a drop of brown - would make it perfect !
It would also decrease the sharp contrast between light desert and dark mountins - when flying at 2000m-4000m altitude... or higher.

Ok lets see if i can resaturate this a little
