Abandoned botanical research greenhouse at dusk, massive geodesic glass dome with rusted iron framework, dying exotic plants and overgrown vines creeping across broken tables, wilting orchids and philodendrons in cracked terracotta pots, weathered leather-bound research journals scattered across moss-covered floor, fading amber daylight transitioning to cool blue twilight through shattered glass panels, hand-painted aesthetic with visible brushstrokes, watercolor texture, frame-by-frame animation quality, Unreal Engine 5 render with raytracing and global illumination, volumetric light rays piercing through dust motes, subtle paper grain, melancholic contemplative mood, soft ambient occlusion, PBR materials, cinematic composition with strong diagonal leading lines toward glowing dome apex
