Very cool and well performed image. But light (above every image), not sure. As explaned bye the title (dadadadra) you are using advanced light sorce but arent we always.
I like the technique but am unsure of the composition. All of the clothespins are presented in the same angle with little to distinguish any one in particular from the others. I notice the slanted position of the one, but feel that a different angle (of the camera on the pins) or arrangment of the pins might make this more compelling. The raindrops are cool, and that should be the focus of this shot. Instead, my eyes are drawn to the pins, but don't find a lot of interest there. Aside from those issues, I like the frozen aspect of the water and your exposure is well done.
