Risograph Poster Style Transfer

Create a standalone 3:4 vertical contemporary risograph-style art poster based on the original photograph. Preserve the woman's silhouette, facial character so the scene remains immediately recognizable. Use bold simplified shapes, rough ink edges, visible risograph grain, slight color misregistration, imperfect printing and handmade texture. Background should be warm cream paper with extensive negative space. Reduce the entire image to only four colors: navy blue, warm cream, mustard yellow and muted red. Keep the composition clean and graphic with the woman and motorcycle forming one strong central illustration. Add only tiny understated editorial text if needed. Aesthetic: Japanese design magazine, independent art print, vintage motorsport poster, sophisticated and collectible.
