Pittsburgh Ambient Art

So my incredibly, fantastically, amazingly, super-duper talented husband, John, likes to photograph ambient art in his spare time ('cuz we have so much of that). I was just thinking I might get one printed on canvas for a room in our home but can't decide which of the 3 below I like best. Then I realized I could bring it to the masses and ask that you let me know your thoughts on which you like best and why!
