To be honest, I'm going to disagree with these comments regarding over-exposure. Firstly, your photos are all exposed well, but yes, in many, the sky is over exposed. What navyplaya, and soa brushed over were the fact that your overexposure of the sky is a stylistic feature of the shot, and moreso, an element of personal style developed over years of photography. I personally like over exposed skies by a stop or two, it brings balance to the photo.
