These are good, looks like you might have been shooting in full daylight. This may have left your sky"overexposed" as well as the statue"underexposed". Work on where you meter from. I have learned the proper place to meter from is somewhere close in between the darkest tone and the lightest tone you are concerned with properly exposing then adjust 1/2 a stop either way.
it was actually cloudy and overcast all day...but it was taken in open courtyard and the walls were white in the background...Im still using the Auto setting...trying to practice composition, shot placement and the basics with out having to figure outthe technical adjustments for the camera. As I continue I will start to switch over to the manual modes
