Create a trendy 3:4 vertical fashion poster using the uploaded portrait as reference. Convert the subject to high-contrast black-and-white duotone on a solid bright teal background. Keep stylish hair, beard, and a confident editorial pose. Dress him in an oversized double-breasted plaid wool overcoat over a ribbed turtleneck sweater, hands in pockets. Add playful white hand-drawn doodles (crown, stars, planets, dotted circles, motion lines, brush swooshes) around the figure. Include bold handwritten text “SAY HELLO” with a small doodle mustache underneath. Modern streetwear-meets-collage fashion magazine aesthetic, clean composition, centered mid-thigh crop.
