Dark monster crouching in cave with top light AI Image Prompt

Subject: A tall humanoid monster with a human-like posture, extremely muscular and robust, covered in rough scales of dark gray nearly brown-black, with bone spurs protruding from the back and shoulders, a ferocious face with fangs exposed, eyes radiating a fierce glare, short sharp bone spikes on the five fingers of the huge hands, nails slightly protruding beyond the fingertips. Action: Crouching in a ready-to-pounce stance, limbs tense, preparing to leap forward. Scene: Dim and damp rocky cave, ground covered with gravel and moss, background filled with diffuse gray-white mist, faint rock wall contours visible in the distance. Lighting: A beam of cool-toned Tyndall top light penetrating the mist from above, reflected light in the cave clearly illuminating the monster's details and face, creating strong contrast, with muscle lines and scale textures prominently highlighted, overall atmosphere eerie and oppressive. Style: Hyper-realistic, dark fantasy, cinematic CG quality, 4K ultra HD, rich in detail, next-gen game modeling style.
