I really like the rays you have in this shot. I think the flare look really works. However the ground seems to be lacking contrast. Perhaps a layer with a boost of contrast or some dodging and burning would have helped IMO. Great shot non the less.
I like the lens flare in this, and the juxtaposition of solar versus manmade power. The foreground and sky are both very similar in tone is this monochromatic presentation - a bit more separation, particularly of the poles against the sky - would give this a bit more "punch" I think.
