Hi,
From a pro point of view,
1. The car in the foreground ruins the photograph. In addition, the building is cut off at the left. The position this was taken from was all wrong. On the plus side, the colour / exposure is quite good.
2. The frame is crooked, this is almost always a no-no and throws this image off immediately. The water in the foreground does not make an interesting subject, this probably should have been shot a little higher up.
3. Very similar to a shot I took in France. Again the image is crooked so this is constantly catching my eye. For me the overall image is too dark, I'd like to see it exposed more. I'd also have waited until the person in front had left the frame, sometimes people add to an image but I don't think this is the case here.
4. The positioning of the image is too high, there is too much sky and not enough in the foreground, with some of the interesting images being cut off. As the last time, it's a little underexposed for me. I think as well the wide angle used has flattened the image, this is particularly noticeable in the lamp on the right hand side of the frame.
