There are no tacks in this image. ;) The color and focus are a little off but the concept is good. Think a white background would have worked better. 6 for the originality
Perhaps it was a choice to use warm light for this shot, but I wonder whether it makes things look muddy in a way that detracts from the photo? The golden and red pins probably are improved by the look. The green and violet pins take on a moody smoky look which is interesting. I think it is the muddiness of the dark shadows that bother me most, and the odd color of the background highlights. ... Okay, after photoshopping the incandescent light out of it I realize that I'm no happier with the photo. I really love its colorful transparent elements individually, but there is something about the composition that still bothers me.
