A storm is coming
The muted colours and the textures of the water, roof and wall really work for me here - the building is kind of grim which matches the sky and water has just been turned black by the reflections of the clouds. About ten minutes after I made this photo the rain clouds you can see arrived and they were torrential. My 40 year old Minolta CLE survived just fine even though there's no real attempt at weather sealing, my shiny new noise cancelling Bluetooth headphones not so much.
