As for some hopefully constructive criticism...some of your images look underexposed. First of all, you were using spot metering for most of these shots(did you intend to?). That is generally not advisable in all but the hardest lighting conditions(think spot lighting on a performer on stage). This could be the reason for some of the underexposure. IF you place the spot metering circle over a white area of the image, you will underexpose the entire image.
Thanks, my camera is normally on spot metering, because most of my shots are of little children and I want the focus to be on them and I didn't even think about moving it. What should it have been on???? That does make sense why some of my sky is blown out. Thanks for the advise.
