The quality of your image really lets you down here, sorry. It appears quite pixelated on my screen, plus your horizon seems to need just a tad of CW rotation. Good idea for the challenge theme though.
Nice colours, but there's too much JPEG artifacting, especially around the sun. The noise is very distracting as well. The sun is too in the centre for the composition to be effective, and I can't help wishing for something else in the picture to add interest. 4
