General feedback. Going through old files from when Toronto was covered by ice.
(If this is a composite, etc. please be honest with your techniques to help others learn)
Well this is pretty cool, both literally and figuratively. I like the light and the warm/cool contrast that it creates. The processing of the ice looks right on the money to me. I also like the concept of filling the frame with the radial pattern of the tree. The ice against the blue sky creates a very dramatic look.
My suggestions for tweaks include evening out the luminosity of the blue, the URC has really dark blues due to the use a wide lens and/or polarizer. I would also crop away a bit of the bottom of the image, IMO the trunks get a little busy there, and pull your eye away from the ice. Here is a rework that reflects both of my comments.
I was going to say that the harsh light conditions have hurt this image but actually you have used the dark blacks to your advantage very nicely in this composition.
