Bold Black and White Pointing Hand

"Create a bold high-contrast black and white illustration of a single arm and hand pointing forcefully to the lower right, fingers extended in a commanding 'get in there' gesture, rendered in a rough halftone screen-print texture like a vintage stencil spray-paint style. Strong dramatic lighting, gritty grain texture on the skin, isolated on a transparent background, no text, designed to be paired below with custom wording, dynamic diagonal composition for a t-shirt print."
