I rarely give post-processing advice (cause I'm a total novice), but maybe clone out the lens flare dots. The sun is awesome, and so are the beams coming off of it. But the white dots... not so much.
I also really like the perspective, you mustve gotten really low to the ground to capture! Maybe a little PP will add to the image, fix up the curves and things a bit.
The foreground is underexposed quiye a bit so I added some fill and contrast, touched up the lens flares best I could with so small an image and your sensor needs cleaning, I fixed the sensor spots.
I think KmH is right that the foreground is underexposed, but IMHO those edits make it look a little radioactive (especially the sky). I'd maybe tone down the foreground a smidgen and mask the original sky back in.
the perspective of the photograph is great, you have shot it from down below... may be needs a little bit of tweek regarding color correction.. and i also would try it in black and white for contrast
