Breathtaking full-body ethereal and deeply unsettling portrait of grotesque Tengu yokai from Japanese folklore, blending realistic Dreamcore aesthetics with subtle psychological horror and soft surrealism. Tall imposing Tengu with red skin, massive crow wings folded behind, long nose and piercing yellow eyes, feathers mixed with coarse hair. Ancient monk robes torn and weathered, full-body standing pose, wings slightly spread, staring down at viewer with arrogant soul-piercing eyes. Vast liminal dreamcore plain with soft pastel fog and low-hanging mist in gentle pastel hues (pale pink, lavender, mint, ivory) mixed with desaturated grays. Far distance: faint blurred silhouettes of old distorted abandoned houses and rooftops emerging from thick haze. Atmosphere: infinite, silent, mentally heavy. Style: Hyper-realistic grotesque Dreamcore mixed with soft surreal 3D render and analog film photography. Lighting: Extremely soft diffused pastel lighting with heavy bloom, volumetric fog, gentle god rays filtering through mist, very low contrast, dreamy yet oppressively unsettling. Camera: Extreme full-body cinematic wide-angle shot, gentle depth of field with sharp focus on creature's face and upper body. Slight film grain and soft ethereal haze. Color Palette: Soft pastel tones heavily desaturated with muted dreamcore grays for melancholic psychologically terrifying mood.
