Stunning sunset

Friday
I had been for my usual walk down to the river and along to Hércy, and I was walking back up from the river as I saw this magnificent sunset evolve. Unfortunately I was surrounded by houses and rooftops, so I couldn't get an uninterrupted view of it, as it was really quite extensive. I wished I had lingered longer by the river for a more uncluttered view, but although I had noticed beautiful cloud formations as I was walking down, I unfortunately didn't think in terms of that possibly resulting in a good sunset!
