Well, in this image you put the top of the arrow off center and you also accomplished limited depth of field.
Unfortunately, while you certainly met the Challenge, the voters didn't score your effort very well. I wonder if it was because the depth of field was so shallow. The viewer had to work a little to find those sharp arrow tops and when that happens...the score suffers. Then too, once the Challenge was met, I'm not sure a viewer would find much of interest to keep him/her in the frame, so that may have played a role as well.
But you have some fine work in your portfolio including your nice tree pic just a week or so ago. (Congratulations on your ribbon, by the way)
I'll look forward to seeing more of your work on DPC.
It took me a second but I get it ... 120 ... I like the colors and wish the top left corner (the wall) wasn't gray, but I see that you couldn't crop it out for this off-center image.
