I really like this - great clouds and its a eye-catching subject. Since this is the Critique I guess the only "Bad" part which is the back Crane does not have much detail as you go up the Boom. But that is nitpicking. I would be very happy if this was my photo with the subject.
I like the composition and the contrasts within your photo. The cloud formation seems to echo the jib of the cranes which is also a strong element to your picture. My only criticism is the white spots within the clouds which I feel you should have spotted out before scanning your print.
