Ultra-realistic photograph of a squirrel dressed as a superhero, wearing a sleek black costume and striking a heroic pose. The setting is a desolate cityscape with towering ruined buildings, under a turbulent, stormy sky. The scene is captured in 8k ultra high definition with a DSLR camera, featuring soft, cinematic lighting and enhanced film grain texture, reminiscent of a shot taken with a Fujifilm XT3. The squirrel’s eyes are intense with determination, and it stands perched above the city, embodying a guardian-like presence.
