|The sunrays are interesting. However, I think you should have waited a couple of minutes, to let the sun set further, Maybe you'd have lost the rays, but the sky wouldn't be as blown out, perhaps with a nich red hue instead.
A bit of fill flash might have been good.
But if you wanted to stick with this, you could have done more in PP (provided you have the SW, of course). Adding some contrast with Curves springs to mind (to reduce the haze), followed by some tweaking with Shadows and Highlights, perhaps.
