You wanted me to write you a critique for this image. As I tell everyone I write a critique for; don't mind the stars.
I think you've done a great job with the settings. You can't really do much about the cameras way of interpreting the pixels. The only thing I can tell you about photographing the sun directly: I wouldn't take my chances without any kind of filter as directsunlight may destroy your autofocusing-motor.
Post-Processing: I'd recommend you to look up on how to remove banding in images. There are a few ways this can be done in photoshop. Banding is the direct transitions between colors which is clearly visible as half circles radiating from the sun. If you remove/dampen the banding in the sky including the sun it'll look much smoother to the eye. I would also use the unsharpenmask in photoshop to shapen the edges of the mountains bodering to the sky and the silhouette of the grass in the foreground. Also make sure that you go over the foreground with a black brush, to ensure that there aren't any gray pixels in there.
These three steps will not drastically improve your image, but it will give you a very professional look to it.
Summary: You got a great image here and I'm sure this is something many people would want hanging at their summerhut or similar. It has a very majestic feel to it. So as mentioned; banding and sharpening.
