Very nice work, love its dynamics and the sky makes it for me, it gives the picture a strong atmospheric feeling. What I don't like is that "white" big bright triangle at the bottom. Just hurts my eyes.
I like the way the triangle at the bottom highlights your watermark/name. Unless the buildings in the background are significant for some reason, I would loose them. They distract my eye...all lines lead from the car back to those buildings, which takes away from that magnificent sky/mountain background.
