Sunsets are wonderful. You may have seen 1000 before the one you now see and you'll still be amazed over the one you're seeing just now!
Wonderful colours.
The photo feels a bit fuzzy, though, even though I can see that the tree tops and thos faraway posts in the part where the trees are lowest look sharp.
I think that if I had taken this photo, I'd have processed it some in Photoshop, only mildly, but I would ... may I try some?
Besides LaFoto's excellent techniques there's also one or more pictures within every photograph. It's like, some kind or law or something. We can get to them by cropping more and scaling less. In yours I see an awesomely beautiful shot within your shot (actually several but just one for now. ).
See where the tree-line dips down to a flat place with what looks like 2 telephone poles in it? Imagine cropping the image to about 2.5 or 3 times the width of that flat place - with the flat-place centered and the general tree-line toward the bottom. Extend the crop box up as high as you'd like but not into the blues. Crop that, apply LaFoto's techniques, scale it for the web and I bet you'll be very very pleased with those results.
