early morning mist over swindon

Taken at 6:30am from Bassett Down overlooking Swindon and the M4 motorway ( both hidden by the mist).
It has been post processed only a little. i found too much post-processing creates immense noise in the mist, so it has been slightly colour tweaked and slightly high pass sharpened. It has also been 'clarified' in PSP to bring out the mist detail. Again, your thoughts.
