Perfect for this contest. What a contrast and not only in the subject matter but throughout the well rendered photograph. Your tonal ranges are spot on with white to black. The focus is spot on, you have no technical distractions...your choice of monotone keeps us focused on opposites versus on colour (smooth move)...the light is good and your could have overexposed because of the time of day (harsh contrast) but you didn't ...you knew what you were doing and it shows. Top of the shelf.

thanks still for the comments
