The entire image displays 6 independent handheld signs. Each sign is fully visible, separated from the others, with no overlapping or merging into a single large board. They are arranged in a clear 2-column × 3-row layout with comfortable negative space. The background is clean, solid white, highlighting each individual sign. Each case is presented as a single image; do not merge multiple cases together. Overall style requirements: Refer to high-fidelity commercial promotional handheld sign materials. The visuals must have a mature commercial feel, originality, and strong detail. Avoid a crude, overly flat, or kindergarten-sticker aesthetic. Each sign must feature a distinct multi-layered structure: thick white outer stroke, colored custom-shaped base plate, inner highlight stroke, slight 3D depth, moderate drop shadows, subtle gradients, rich but organized 3D icons, large main text, and small auxiliary labels. The overall look should resemble real, manufacturable KT board or PVC custom-cut handheld signs with complete edges, stable structure, suitable for die-cutting, and perfect for handheld photography. The color scheme should revolve around [Main Color], complemented by [Secondary Color] and [Accent Color], ensuring the set is eye-catching, unified, and festive. Avoid monochromatic or overly plain palettes. Icon elements should center around [Industry Keywords], incorporating [Icon Element 1], [Icon Element 2], [Icon Element 3], [Icon Element 4], [Icon Element 5], etc., to enhance the event atmosphere and finished product quality. Please generate the following 6 independent handheld sign designs, ensuring each has an appropriate custom silhouette and icon configuration: 1. [Copy 1] 2. [Copy 2] 3. [Copy 3] 4. [Copy 4] 5. [Copy 5] 6. [Copy 6] The 6 sign shapes must vary; do not make them all identical. Flexibly use different custom silhouettes such as speech bubbles, dialogue boxes, explosion shapes, arrow frames, rounded labels, coupon frames, product-shaped frames, and lightning bolts, while maintaining a unified series aesthetic. The font must be bold Chinese promotional style; the main information should be clear and striking, suitable for long-distance recognition. If the copy includes numbers, discounts, prices, quantities, or gifts, these figures and keywords must be significantly enlarged as the visual focal point. Emphasis: The entire set should look like a real-world handheld sign material scheme used in [Applicable Scenario], balancing photo-op appeal with promotional impact and commercial viability. Avoid: overly flat or crude designs, children's sticker aesthetics, six identical cloud frames, sparse icons, lack of depth, lack of commercial event feel, weak typography, or looking like digital overlays rather than physical handheld signs. Final output requirements: High definition, white background, 9:16 vertical aspect ratio, 6 independent handheld signs displayed within a single image, rich in detail, highly original, aesthetically pleasing, and suitable for reference in subsequent production.
