I think these are the two strongest images of your Bologna set composition-wise. In the first one, I like how the two tall buildings frame the subject; the subject might be a bit dark, though. In the second one, I absolutely LOVE how the roofs guide the eye throughout the picture; it seems just a tad overexposed, but it could be just my monitor.
Thanks! I'll get back in PS and see if I can lighten that subject up a bit in #1. I must say that there was all sorts of good photographic material on this trip -- I wish I had brought my 10-20 with me too. I have more to come ... still slowly inching through a gazillion RAW images. The roof top was taken from the top of the tower -- the climb was long, but worth it. The tower leans too ... creepy.
