Wide establishing shot, 28mm lens, deep depth of field, off-center composition with foreground texture partially veiling the frame, cinematic widescreen 16:9 landscape orientation, gritty UK night visualizer mood. No human figure, no face, no performer, no text, no logos, no readable writing anywhere in the frame."
