Interesting capture of detail in something frequently looked at without really being seen. Calling attention to such parts of life is a good reason to make images. I never realized that the geometric shapes forming these figures are not always uniform dots. The mild distortion from shooting with the camera lower than the subject suggests a space ailien portrait. Including the last bit of heel in the lower corner might have been a minor improvement, but noticing the vibrance of transmitted instead of reflected light and acting on the impulse to capture is a photographic habit worthy of nurturing.
