Oh, this is so extraordinary! Skies are so interesting, and you captured this one beautifully
I quite the composition as is, the way you have the structures outlining the sun on the bottom is excellent! Perhaps you could've shifted your camera down a tad, as the bottom is a little crowded, but nice work!
The colors are also lovely! The different shades of red and orange catch your eye quickly and make the photo much more interesting. There is some overexposure with the sun, but it works with the rest of the photo so I don't think it's too big of a deal.
The focus is a little too blurry for my taste; especially in the clouds. I know you probably focused on the sun, but with a landscape you want as much detail as possible.
