(yeah a touch blown or banded, maybe right near the sun, but it's very high DR I bet so tricky, also some of that is also probably sRGB clipping more than anything. It would be cool to see it posted in ProphotoRGB, I bet a couple glowing bands show up in clouds too then, but it looks very nice as is too.)
I love the composition here. I will say that the colors do seem a bit over the top, especially in the blues and the clouds. The sun also looks like a nuclear bomb in the distance! With a bit more processing restraint, I would really enjoy this one a ton.
