its a nice photo,but there is nothing that really catches my eye.imo sunset shots are fairly common so to make them stand out in the crowd they need some sort of feature in the foreground;perhaps a boat,a tree or some birds etc.
Great texture on the clouds. Your horizon is a bit tilted, and you can easily fix that in PS. Under the eyedroper tool, select 'measure', and drag the little line across your horizon, making sure to line it up on both ends so that it follows your horizon. Then go to 'image--->rotate---->arbitrary'. It will tell you the angle the image will be rotated, press OK. You'll get funny white spaces on every side which you have to crop out, but honestly, I think a tilted horizon is not worth the price of a little bit of your image.
