Great terrain, I love it! Good composition too.
It definitely looks hot, but I have trouble reconciling that with the presence of low hanging clouds, usually associated with cool mornings.
I wonder what you are trying to expose for in this image? Sky? Surface?
The sky is white, which indicates over-exposure of the sky with the intention of exposing for the terrain. That's fine, but then the terrain's lighting would be more contrasty, with deeper/darker shadows. Now it looks like both are over-exposed and it makes it look flat'ish.
