Astronaut Faces Colossal Alien Megastructure in Space

the prompt

15-Second Sci-Fi Cinematic
A lone astronaut stands on the edge of a colossal alien megastructure  floating above a shattered planet as a mysterious blue signal pulses  across the sky. Massive ring worlds rotate slowly in the distance while  swarms of tiny drones awaken from the darkness. The astronaut cautiously  steps forward as gravity bends around them, fragments of rock levitate,  and glowing alien glyphs illuminate beneath their boots. Suddenly, an  enormous biomechanical entity emerges from the structure, its eyes  igniting with celestial energy. 

The camera performs a slow cinematic  push-in, transitions into an orbit shot around the astronaut, then  accelerates into a dramatic wide reveal of the colossal alien machine dwarfing the landscape.
