Paziente maniaco legato a una sedia in una cella carceraria in pixel art

Create a high-quality art scene: A man in a tattered white restraint vest, strapped to a cold metal chair. His expression is manic, featuring a wide, toothy grin and wild, unkempt hair. visible square pixels, stark dithering for texture. The setting is a dim, grime-streaked cell. A single overhead pixelated light source casts harsh, long shadows. Limited palette: clinical grays, sickly yellows, and deep shadow blacks. Sprite-based composition with a slightly tilted "Dutch angle" to enhance the feeling of madness. aesthetic with solid color lighting and no modern gradients.
