Personally i think the colours are too saturated, that or too fluro, later on this week i plan to get photoshopping and see if i can get the terrain to look normal.
The clouds also look very... il2fb... I hope something is changed before release, i have never EVER EVER EVER seen a cloud that is comparable to a ball of cotton wool in real life
The whole fluro thing with the ground is probably due to lighting, the afternoon/night shots look fine in that respect.
