日式夏季浮世繪風格團扇，飾有牽牛花與河流圖案，現代平面設計感

提示詞

Create a stylish contemporary Japanese summer illustration on a clean white vertical canvas, centered on one traditional round uchiwa fan with a bamboo handle. The fan face should be teal and deep blue with layered translucent graphic shapes, combining ukiyo-e-inspired motifs and modern poster design. Show exactly 6 main decorative motif groups on and around the fan: 1) a white flowing river or wave ribbon sweeping from the lower left across the fan, 2) green bamboo leaves clustered across the upper left edge, 3) morning glory flowers on the right side with one large pink bloom, one large navy bloom, and several small dark blue blossoms, 4) round green leaves near the flowers and lower left, 5) a partial pale parasol-like circular arc with cream and coral bands behind the upper right of the fan, and 6) abstract halftone dots, splatter marks, and diagonal geometric strokes in turquoise, lime green, coral pink, and navy around the fan. Render the fan ribs and frame as realistic pale bamboo, with many thin spokes radiating from the base, a small turquoise binding at the handle joint, and a natural bamboo handle extending downward. Use a crisp mixed-media look: flat vector illustration blended with subtle paper texture, screen-print halftones, translucent overlays, fine white vertical fan fold lines, and slight shadows to give the fan depth. Keep the composition airy and elegant with generous white space. Add a small date and artist signature in the bottom right reading May 15, 2026 and Oyagi. Use a refined fashionable illustration mood inspired by Japanese summer, with dominant colors teal, indigo, lime green, white, coral pink. No extra text, no watermark, no border.
