|Greetings from the Critique Club!
I can see where you want to go with this shot, Daniel, and you're close but not quite there. I also love those gorgeous big fluffy pink and blue cotton-candy clouds, and you only have a couple of minutes to try and get them before the light changes. Mainly, with the buildings being such a heavy element (in all terms of the word - they're visually blocky and sharp-edged in contrast to the clouds). They are also in such sharp focus they can't help but draw the eye to themselves. Having the trees there adds clutter to the shot. It may have been a better idea to just shoot straight up from where you were, as there was probably some nice pinky-blue tones overhead, and go with that. Either that or just a square crop of the left segment of your shot, so the leaning tower is the only hard-edged element in there and emphasizing the clouds instead of overwhelming them.
Hope this helps, please keep shooting and entering!
