photorealistic scene of a rowdy group of chubby Japanese salarymen in their 30s-40s howling with laughter during a boozy karaoke after-work party in a smoky izakaya room lit by warm neon red and amber lights, hazy glows highlighting flushed sweaty faces, loosened ties, and rumpled suits for authentic tipsy vibe, foreground spotlights a plump drunken salaryman with disheveled black hair under a silly bear mascot hood tilted crookedly on his head, his round belly protruding as he clumsily lifts his wrinkled dress shirt with one hand to reveal a hand-drawn cartoon face inked on his bare skin—oversized googly eyes rolling in mock surprise and a wildly grinning mouth with tongue sticking out—fresh marker lines with playful smudges, his other hand fumbles a wireless microphone pressed sloppily against the cartoon mouth as if it's belting out a drunken duet, midground shows two more hefty colleagues in animal hoods (one rabbit, one panda) mimicking the ridiculous pose on their own bellied masterpieces with crossed eyes for added goofiness, they're staggering against each other in belly-shaking guffaws, background buzzes with more suited friends clinking beer mugs, snapping blurry selfies, and belting choruses off-pitch, dynamic vertical composition channeling the eye from foreground's sloppy hilarity to the infectious office camaraderie chaos, volumetric lighting softly caressing chubby contours, detailed fabric wrinkles, glistening sweat beads, and vivid ink doodles on exposed torsos, high-fidelity emotional rush of tipsy absurdity and rowdy bonds, cinematic depth of field with sharp focus on hoods, bellies, and mics, 8k resolution, aspect ratio 9:16
