I missed this one during the challenge Marc. I think this one is a good study yet somehow I wish the DOF was smaller to have evrything in focus. It seems like the WB is a bit off in this image but nothing to really distract the viewers attention. Great placement and good score overall!
In a way I wish it was the dominos at the back of the picture which were in focus. the shwishing shape wants to pull my eye from the from of the picture to the back, plus in regards to falling dominos all the tension lies in the first one falling over. Still a pretty nice picture though :-).
