Moody cinematic promotional artwork for a Malayalam horror web series. Interior of an abandoned Kerala tharavadu ancestral house at night, carved dark wooden pillars, a single oil lamp casting flickering amber light across peeling walls, deep crimson shadows creeping in the corners, faint fog drifting through an open doorway. High-contrast, atmospheric, spectral, no people. Feels like a prestige thriller poster. Cinematic film grain, rich blacks.
