Great subject for a macro. The sharp focus in the center works very nicely. As a warm weather lover, I like to think of frozen dew as nature compensating us with beauty after hammering us with a cold morning.
I like the subject. The vignetting is nice. The darkness and depth of field look good to me. I like that your attention is brought by both the light and focus to a certain area. This works as a photograph on it's own and really makes it a nice wallpaper if used for that. Peaceful.
