Art style: Cinematic Realistic.
A dark dungeon classroom with towering cabinets of potion ingredients. Snape sits behind his heavy wooden desk, holding the silver goblet to his lips. His eyes are suddenly blown wide open in profound shock, staring blankly ahead. Close-up shot from a low angle, emphasizing his dramatic reaction. Harsh, eerie green lighting casts deep shadows under his cheekbones and nose, highlighting his pale skin. The atmosphere is jarring and surreal, dominated by sickly greens, deep blacks, and a sudden flash of warm magenta in his eyes.

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image entirely in "Cinematic Realistic" style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "Cinematic Realistic". Keep the subject, composition, camera angle, lighting direction, and colour palette from the description above — but EVERY surface, skin, fabric, material, and environmental element must be rendered in the "Cinematic Realistic" idiom, not in any other medium.
