Paper Tear Flat Illustration Poster

Generate a vertical flat illustration poster centered on the theme "The sun stands at the door of the night". First, cover the canvas with a high-purity structural color derived from the thematic emotion, acting as a low-noise colored paper surface that provides occlusion, whitespace, and breathing room. Do not establish real depth or a full scene; instead, treat the background as a closed skin with slight paper texture, scanning grain, and minor printing irregularities. The main visual should not be fully displayed in front of the background but should emerge from an irregular horizontal rift torn from the upper-middle part of the paper surface. The rift should feature white paper fibers, dark inner edges, sharp jagged fringes, and a slight outward fold, as if the inner world is pushing the paper open. The theme is revealed from within the rift only through key cropped segments, recognizable edges, a small but intense focal point, and high-density fragments; the complete outline is swallowed by the paper, and secondary information is obscured, leaving only the physical tension, material texture, and symbolic core that best define the theme. The focal point area is small but must dominate the first glance like a point of gaze, semi-enclosed by a foreground shape. This occluding shape, transformed from thematic semantics, features gesture-like curves, close-up tactile quality, and horizontal guidance, covering part of the focus to create a visual resistance of being pushed open, discovered, or protected. Fragments derived from the theme gather at the edges of the rift, forming soft boundaries along the top, bottom, left, and right, partially overflowing onto the paper surface without spreading evenly; fragments are both content and part of the rift structure, pushing the internal world toward the external void through density, direction, and color dots. Color maintains clear hierarchies: the largest area of structural color remains pure, the rift interior uses medium areas of vital or material colors, and small highlights of emotional color flicker only near edges and the focus. Dark anchor points are placed at the focus outline, inner edges, and key occlusions, while the highest brightness is used only for torn edges, tiny highlights, and material cuts. The overall style is finished with hand-painted flat color blocks, clear blue-black or dark line drawings, slight paper grain, scanning noise, and uneven printing particles, allowing the object to be recognized by partial contours and density even while partially hidden. Retain significant solid color breathing room in the lower or quietest empty zones. If text appears, it should only serve as meticulous titles, numbers, short phrases, or miniature footnotes, using restrained publication typography with fine strokes, wide spacing, and low interference, collaborating with whitespace without distracting from the focus inside the rift. The entire image creates a cover-like feel where a solid-colored void suppresses the inner world while the rift exposes thematic secrets, stably maintaining order among the quiet paper, upper-middle break, high-density interior, single strong focus, foreground occlusion, edge fragments, dark anchors, and low-toned text.
