Extreme close-up cinematic scene of a futuristic astronaut helmet with a large jagged crack across the reflective visor, a vivid bioluminescent purple tentacle bursting out through the shattered glass, textured suction cups glistening with moisture and iridescent slime, tiny glass shards suspended mid-air. Moody cold-blue ambient lighting with neon bokeh in the background, subtle magenta and cyan rim lights highlighting contours of the helmet and tentacle, high-contrast specular highlights and soft volumetric fog. Photorealistic details: scratched metal, matte and glossy surfaces, visible fasteners and seams on suit, shallow depth of field, dramatic low-angle composition, tight crop on helmet and tentacle, high resolution, cinematic color grading, slight film grain and chromatic aberration for realism, intense eerie atmosphere, dynamic motion and tension.
