The first and last shots get my vote. I love the red handles in the first frame. Are these valves supposed to relieve pressure from the Dam, that is about to burst. "Open all valves!!!"
Even though the last frame is greyscale I still love it. The light shining in is nothing short of amazing.
ha ha, im sure you already know which are my favs?
ha ha - yep - its #1 and #2!
#1 - if i would be picky (you know im not -) ) - i 'd try to take this shot from a different angle maybe...(a bit different) - > just to make the composition more centered (to move it a bit to the right), and move away (just a one or two mm!)last cock(left) from the center one.....hmmm....was it clear with my english? - (im sure you know what im talking about!- )
