I maped out all the dark structural areas first, not much detail just main shapes and then the lighter sky. Tricky when it changed so quickly but finished in the studio. I wanted it to feel like that strong light shinning just before it goes down and mellows.
In mid painting flow when a photographer quite far away with a zoom lens was aiming at me. I called after him once he'd taken it but it was way too loud with the traffic on the Chelsea Embankment next me, he disappeared but kindly looked me up - from my website on my Open Box M pochade.
Thank you Wojciech Jarowslaw Pawlowski for the lovely sunlit photo.
