I actually love the first image.
Small complaint, it's slightly crooked. It's in that "meant to be straight" zone, rather than the I meant to make it crooked zone. My opinion.
Number 5 for me, and it's not even close. Beautiful abstract! I think it'd look even more balanced if you cropped the tiniest bit on the left-hand side. How tiny? Maybe one window.
Lovely photo's, clever on the first one and the rest are really simple and nice. On the second one, i don't know if its just me but the middle column looks crooked
