โปสเตอร์เซนฤดูใบไม้ร่วงพร้อมนักเดินทาง

An Eastern Zen minimalist cover poster illustration with a bright, luminous atmosphere. An [ancient-style young traveler] in flowing [pale cyan-gray robes] stands turned slightly sideways on a long flight of [clean cream-white stone stairs], lightly holding a [beige oil-paper umbrella] in their right hand. Scattered red maple leaves rest along the steps, with subtle dappled tree shadows. A vivid, clear blue sky extends in the background. Composition is vertical 9:16, with the stairs leading from bottom to top, the traveler positioned in the lower-middle section, and generous clean negative space reserved at the top for title placement. Crisp lighting with bright sunlight, clean edges, flat modern poster aesthetic, and an extremely delicate fine paper texture. High-key cream-white palette with vibrant maple-red accents and pure sky blue, with no murky yellow cast.
