The image establishes a clear, stable vertical axis, with the visual elements on both sides pushing the gaze toward the center. The two sides are not merely symmetrical decoration but truly participate in the theme's expression—they can be figures, dance sleeves, smoke, objects, architecture, projections, material silhouettes, or different states of the same theme. Flexibly choose the framing method based on the theme: figure actions use pose, sleeves, fabric, and body curves to frame the central negative form; light-and-shadow projection lets shadows or bright areas on both sides converge toward the center; positive-negative contrast uses original and product, solid and imprint, reverse-carving and direct print to form the axis relationship; smoke and airflow let two continuous rising or swirling lines encircle the center; solid silhouettes enclose the central zone through the edges of objects, architecture, or natural forms. The title must be the core of the image and truly participate in the composition. Use large vertical, horizontal, offset, split, or cross-zone typography; do not always apply the same "four-character title" format. The text may lightly interweave, overlap, or touch the edges of the subject, but must stay clearly legible. The overall information density should be richer than an ordinary poster; add a little exhibition information on the axis, side columns, and bottom, and a small research module such as motion trajectory, process steps, airflow changes, or structural diagram, making the image resemble a mature museum poster and editorial design. Control the palette to 3–5 main colors forming clear large color-block relationships. At first glance one should see the side visual forces and the axis focus; at second glance read the title; at third glance discover the connection between the composition method and the theme. Overall requirements: refined, clear, complete, richly layered, with visual impact; avoid mechanical symmetry, fixed-template feel, PPT-style info boxes, meaningless decoration, mottled noise, blurred text, and a low-completion AI look.
