Create a cinematic, urban-style portrait of a man standing confidently with a powerful German Shepherd dog in front of him, set against a gritty brick wall covered in graffiti. The low camera angle emphasizes dominance and strength, with the dog in the foreground, mouth open mid-snarl or bark, exuding energy and intensity. The man stands tall behind the dog, holding the leash firmly, wearing a beige windbreaker with black stripes, black pants, dark sunglasses with amber-tinted lenses, and a black bandana around his neck.
