First Impression:
Very centered. The “Phillips” star in the screw “marks” the spot and keeps drawing my eyes. The top two dark corners were the second place my eyes went, before I focused in on the ice. The ice actually lead my eye to the top right corner.
Composition:
Background and the screw head compete for visual attention with the ice. The ice is not the dominant subject. I’m assuming you wanted the ice as the subject and not the screw.
Subject:
I agree with your comment! I visited your portfolio, and saw some very nice pictures. My guess is that you didn’t have a lot of options with this picture in terms of capturing the ice crystals. Good eyes to see this, even better, you had the camera to capture it! :-)
Technical:
More depth of field would have brought all of the ice in focus, or move the focus point back to one of the ice crystals. Lighting is flat, with no sparkle in the ice.
Summary:
The ice crystals are neat, and make an interesting picture, unfortunately, you entered the Best of 2005, a very tough challenge for this type of picture.
Wow how cool! Not seen anything quite like this before! I think it would look even better with an ice blue tint, but that's just me and my likeness of blue showing through :P
I like the way that the long 'needle' is arranged to point at the corner of the frame, although the shallow DOF seems to have rendered it a little blurred. I imagine that much greater DOF would be difficult in such a close-up, though.
