Hmm, details in the sky are all burnt in the first and last images in the 1st topic. Too much tonality range for the camera to record (dark shadows are very dark and the bright sky was very bright).
You could try for a more balanced exposure the next time. Or better yet, bracket your exposures and layer them in pp (or HDR if you want to take it a step further).
Just my 2 cents worth.
Composition-wise, hmm. There are many strong leading lines produced by the outlines of the buildings, but they don't seem to be leading anywhere? Also, the lamp post and some unidentifiable thing on the right hand side of the very last image are very distracting. Watch out for the corners and edges of your frame too.
