ah nice saturation tropic, bumped it up a bit yes?
The car on the first one really spoils the picture for me, too bad...
The second one is very good indeed, the shack brings much needed contrast to the picture.
3rd one has a lot of promise, but I can't help thinking all the time that a different composition could have made it a stunning picture. Maybe b&w with violent sky, subdued colors... the works.
