Dominican Sunset

This is a photograph of the sunset in Dominica as we drove down from the Syndicate National Park in the Rainforest. A quick storm had just passed creating the fog/mist rising. I only had the chance to ask the driver to briefly stop as I snapped photos from the window so it wasn't the ideal composition and I'm new to the landscape photography thing but this to me represents what I saw.

I double blended this image in CS5, once for highlights and once for shadows. I eliminated two cell towers on one of the peaks and removed some lens flare as well as performed noise reduction.

Any comments or recommendations on I could have better handled the situation technically would be appreciated. Thanks.
