Coastal watching tower, modern architecture, sleek lines, white concrete, large windows, panoramic view, 3/4 composition, dramatic lighting, sunset time, golden hour, seagulls flying overhead, waves crashing against the shore, rocky coastline, beach vegetation, sandy dunes, distant sailboats, lifeguard stand, surfboards leaning against railing, binoculars mounted on tripod, weathered wooden decking, ropes and pulleys, nautical flags flapping in the wind.
