This is a really good shot for the challenge, but there are a couple of details that I think would make it even better. The rust seems slightly out of focus, more depth of field may have been required to capture the full texture of the rust. A list less exposure on the rust would also have helped to separate from the flower. One last very small item, ensure that the lines created by the holes and the seam remain perfectly verticle so you do not get a diagonal that might pull away from the flower. My score will be high... thanks for the creative image.
