Lighting, color, saturation, contrast and hue are all done well.
But those power lines are killers. (As you probably have already deduced from the other comments.) The power pole sticking up above the trees, and the light or white spot in front of the trees are also distractions. Looks like the light is illuminating a flag pole just left of center. (Is this a cemetary?) As this is an avanced editing challenge, I would have cloned them out or shot from a distance and angle where they would have added to the composition.
There also appears to be a very dimly lit road in the foreground. Taking it a bit darker could have turned it into a silhouette, and reduced the distraction here. If you did it using contrast, it might give you a little more definition to your clouds.
I like the idea of having the dark silhouettes however I find the power lines distracting from the dramatic sky. I am also drawn to the white spot in the trees.
Nice sunset! I hate it when those city power lines get in the way though! I don't really mind the pole in the background but the lines in front take away too much :(
Still, excellent pastel colors.
