This is a very nice shot and VERY graphically clean. I would have used a higher (smaller) apeture to get all of the tacks in focus myself, and spaced the tacks in a perfect triangle surround the lower right thirds intersection.
great comp, great color, excellent movement, minimalistic, love the light, a bit soft on the far right tack and left hand corner but not disturbing, great lines, nice job
Very nice graphic image. Nice lines and choice of colors. Paper photography is fun, and the pins add an extra point of interest. Not 100% sure if it would've been better with all the pins tack sharp ;) in focus but this works too.
