A beautiful shot! Lovely colors in the sky and a undercast of clouds. Something rarely seen I suspect. Did you wait another 15 minutes? I am guessing with the high level clouds, a setting sun would turn the underside of the clouds a deep fiery red. Well done.

The clouds in the upper and lower right are brighter than those in the left part of the scene.  In post-processing be careful to be consistent with the rest of the scene.
