Modern risograph flat poster folk style

Create a flat poster in the style of a modern risograph using the attached photo as the reference. Use the colors from the photo as solid, flat color blocks on a warm cream paper background. Include simple hand-drawn black outlines, naïve proportions, minimal facial features, fine hatching textures, visible speckled grain, and slightly imperfect printing for an authentic risograph feel. Keep the shapes clean and graphic, with a playful folk-poster aesthetic and a calm, centered composition. Frame the artwork with a rounded cream border inspired by vintage Japanese illustrated book posters. Aspect ratio: 4:5.
