Create one independent "Second World" poster per upload. Never combine photos. Format: Vertical 3:4 canvas split into two strictly equal horizontal halves, top 50% and bottom 50%. Upper half stays photographic; lower half becomes the continued Second World. They must read as one scene. Upper Half: Keep the photo faithful. Preserve subject, pose, spatial relationships, color atmosphere, and natural light. Do not redesign, repaint, replace, or restage it. Only allow necessary proportional cropping. Continuity: The top-to-bottom connection is the highest priority. Identify one source structure that naturally reaches the center split, such as a road, shoreline, water, reflection, branch, light, architecture, or body movement. This structure must cross the boundary and continue into the lower half. The Second World must begin from the photograph itself, so the same scene passes through the seam and changes physical rules. Transition Edge: The center may use an irregular torn-paper edge, but the tear must follow the source structure, not act as decoration. Allow source elements to touch, follow, break through, or extend beyond it. Never force the same tear shape onto every image. Lower Half: Use ivory paper with subtle fibers and abundant negative space. Continue the chosen structure downward from the exact point where it meets the split, then reinterpret it with restrained photo fragments, cut-paper forms, and minimal black hand-drawn lines. The lower world must remain visibly attached. Never isolate it as a separate portal, window, stage, platform, or floating vignette unless clearly derived from the photo. Second World Logic: Ask: if this structure became touchable, usable, enterable, or changeable, what would it naturally become? Create one image-specific interaction. For example, water may stay attached while being pulled, a road may continue as a drawn path, or light may become something held. Do not mechanically repeat actions. Figures: Add 0-3 tiny black line figures only when useful. They must physically interact with the continued structure. If the source already contains strong human action, add none. Never use figures as decoration. Caption: Add one short handwritten English caption based on the action. Keep it natural, light, and slightly witty. No inspirational quote and no fixed "Same..., different..." phrasing. Style: Real photography above, warm paper below, minimal black line doodle, subtle handmade collage texture, independent-magazine mood, bright, airy, and restrained. The result should feel as if the second world was already hidden inside the photo and simply continued downward. Negative: No detached lower-half illustration, no generic torn-paper template, no isolated portal, no unrelated vignette, no broken continuity, no dense illustration, no random decoration, no crowd, no altered photo colors, no redesign of the upper image, no glossy 3D, no scrapbook clutter, no gibberish text, no watermark, no logo, no UI.

Create one independent high-end editorial poster for each uploaded photo. Never combine photos. FORMAT Strict 3:4 vertical composition with an exact 50/50 horizontal split. The top and bottom halves must be equal in height and visually connected as one refined editorial cover. TOP HALF: ORIGINAL PHOTO Use the original photo faithfully. Preserve the subject, identity, facial features, proportions, pose, clothing, objects, composition, lighting, shadows, atmosphere, and color mood. Keep it fully photorealistic with only subtle premium editorial color grading. Never stylize, distort, replace, or alter the main subject. Extend only surrounding background when necessary, seamlessly and naturally. BOTTOM HALF: HAND-DRAWN ILLUSTRATION Reinterpret the same scene as a minimalist handmade paper illustration. Preserve the recognizable subject, silhouette, pose, key objects, and main visual story. Use delicate imperfect lines, simple acrylic-style flat color shapes, visible brush marks, rough paper texture, organic edges, and subtle handmade imperfections. Keep the illustration small and centered, occupying about 10–20% of the bottom half, with generous negative space. Use a rough white, warm off-white, or pale natural paper background with only minimal environmental details. COLOR Extract colors from the original photo and reduce them to a maximum of 4 restrained, harmonious colors. Use controlled flat color blocks while maintaining subtle paper grain and brush texture. TYPOGRAPHY Optional minimal editorial text only when appropriate, such as a short title, keyword, location, or number. Keep it understated and never force text into the design. STYLE Quiet, poetic, refined, minimal, relaxed, artistic, thoughtful, premium, high-recognition. FINAL Maintain the exact 50/50 split. The top must remain a faithful photograph, while the bottom is a simplified handmade illustration of the same scene. Avoid clutter, excessive colors, heavy typography, artificial effects, or unnecessary details. The result should feel like a premium contemporary independent art publication cover.

Transform the reference photo into a refined travel journal illustration while preserving the original composition, architecture, people, trees, grass, roads, and overall perspective. Use a traditional colored-pencil and watercolor sketch aesthetic, rendered on warm, slightly aged cream-colored paper. Keep the architecture recognizable, but simplify it into expressive hand-drawn forms with visible pencil strokes, loose watercolor washes, subtle paper texture, imperfect contour lines, and soft cross-hatching. Preserve the bright, sunny summer atmosphere, with a gentle blue sky, warm beige buildings, green lawns, people sitting casually on the grass and relaxing, benches, trees, and cars in the distance. Use a soft, vintage travel-sketch color palette with natural imperfections and understated colors. Place the illustration in the lower portion of the page, leaving generous cream-colored negative space around it. Above the illustration, add elegant handwritten text: “Sunny Days”, and below it: “— Good time —”. The overall aesthetic should be minimalist, nostalgic, artistic, and reminiscent of a refined travel magazine, transforming an analog photograph into a personal travel-journal memory—delicate and authentic, with no photorealism.
