I really love these types of photos; they capture a beauty that's not always closely observed by most people.
I noticed you have another version of this, but with a some orange near the top. Personally, I think the all-blue background is better for this one. It fits better with the theme of the picture, I'm guessing winter, and still allows the ice crystals to pop out. Orange just seems to clash too much in my opinion.
This somewhat resembles a shoreline, where the fog is the sea and the ice is the land. The way the fog wraps along the edge of the ice "shore" emphasizes this appearance.
Good job! And, again, good work on capturing a beauty not seen by most people!
