Frozen raindrop

I was trying to take a photo of a blade of grass decorated with frozen raindrops, but not getting what I wanted, when one of the frozen droplets fell off---so I placed that on a frost-covered bench and photographed that instead. I think this could have been sharper, or more dof (not sure), but I do like the air bubbles in the droplet, and the mini droplets on top of it. (Not sure why, but it puts me in mind of a pufferfish :D)
