Well, for sure you need to straighten the horizon. About the photo and the PP, I am not sure about it. It looks like a red and cyan 3D photo. Was the color really like that?
I don't mind a bit of enhancement, but I thought the orange glow gave it a surreal effect and was really great.
And nature's colours are unparalleled, especially at sunset. I don't care what camera and equipment you get, it's impossible to get the full effect of a glorious sunset in a camera. The unedited version is the best in my view.
