This couldn't be more beautiful if you just started from scratch and painted the colors on! Man, this is so pretty and natural even if you manipulated it or not. Love the sun and the single figure. The one patch of green is a nice diversion to all the warm tones. All the textures are just a wonderful piece of eye candy!!!
This is an amazing shot - though it might help to straighten the horizon. It's slightly off kilter - if you can do thast without having to crop too close to the woman I think it would really help.
This is a great pic. Truly beautiful. My only comment would be that the sunrise is "posterized" a bit. You might be able to smooth it out using either a selective gaussian blur or neat image.
