Snow Clouds Approaching

I tried to capture the sense of impending action I felt watching the clouds roll in with the threat of snow showers. I was working quickly trying to find an angle to work with, before it went too dark. The crack seemed a good idea to lead into the frame, but it's not quite in the right spot.

I think the right side of the image doesn't have anything to balance out the rocks. Maybe I should darken the ice, but I don't think that's going to help much. I do like the texture in the foreground snow.
