Looks solid man, I'll nitpick a bit.
Those large, centered icebergs in the mid ground are flattening out in an unpleasant way, mainly the protrusion in the way back. Also, the blue in the drifting ice in the lower right foreground seems a tad too saturated. I think the blue is fine, it adds some nice variation from the gray found in the other ice, but I'd tone it down a bit.
Overall I think the matte looks great, and compliments on all the subtle snowfall you've added to the buildings, it looks convincing.
