Hardcore Sci-Fi Carnivorous Monster in 8K Film Grain AI Image Prompt

Positive prompt: 8K ultra-high-definition master-level artistic masterpiece, professional film photography texture, DaVinci color grading with somber and sophisticated tones, dim and layered image, full of intricate details, biological textures and mechanical structures clearly visible. The subject is a carnivorous monster set in hard sci-fi, full body in the distance, facing the camera directly, full of oppression and rebellion; the monster has rough and thick skin, sharp giant claws, and black-blue precision mechanical structures embedded in its body, strong industrial hardcore texture, biological textures intertwined with mechanical pipelines, hair strands clearly defined, apocalyptic grotesque aesthetic tension fully loaded. Wide-angle slightly low-angle shot to enhance the impact of the form, clean pure white background restrained, contrasting the complex structural details of the monster; front lighting precisely outlines the contour layers, film grain naturally diffuses, strong 1980s retro sci-fi film atmosphere. Overall, it combines the pioneering spirit of concept design with the realistic texture of professional photography, and is a hardcore sci-fi art work full of rebellious spirit. A clear and natural handwritten signature 'only840820' is subtly integrated at the lower right of the frame, with thin strokes hidden in the dark areas, not disrupting the clean texture of the overall concept image. Negative prompt: Background cluttered and not pure white, monster lacks rough skin and sharp claws, missing black-blue precision mechanical structure; perspective is eye-level without wide-angle low-angle tension, lighting is messy without front-light layering; blurry quality with sloppy details, no film grain and DaVinci color grading texture; style is bright and straightforward without dim atmosphere, missing apocalyptic grotesque and retro sci-fi tone, signature too large and conspicuous, overall lacking the rebellious impact and artistic texture of hardcore sci-fi.
