Hi Mark. A very symmetrical and well thought out image, good idea. The decision to go black and white worked. The DOF is deep, everything fully in focus, the detail is fantastic. What strikes me first when I look at this photo is the amazing contrast. The blacks and whites are so subtle!
The composition is good, the angle works here. I think a straight on shot wouldn't have had as much impact. The only thing I would have changed is the crop. Everything in this photo is so symmetrical except for the crop which you can see on the outer ring of the dartboard. I would have cropped it more evenly.
I like the idea but feel that the processing is too extreme. I realise it was probably a deliberate effect but I would have preferred something more natural.
