Event Key Visual with Cartoon Stickers and a Circular Photo Window

[Theme], [Character], contemporary trendy cartoon illustration × Cartoon Graffiti × Sticker Art × playful editorial illustration × neo-retro American cartoon × commercial event KV visual design.

Visual style:
Thick dark brown hand-drawn outlines, uneven line weights, rounded exaggerated cartoon forms, irregular organic geometric color blocks, flat vector fills, and a small amount of hand-drawn texture. Characters adopt exaggerated head-to-body proportions, simplified facial features, playful expressions, and rhythmic movements. High-saturation contrasting colors, with 3–5 main colors designed randomly based on the theme, large areas of solid color fields, and clear warm-cool and brightness contrast.

Core composition:
Horizontal commercial banner with asymmetrical left-right zones, overall using a dense surrounding collage composition.

The left side, about 40%, is the visual headline zone, featuring a huge, irregular, thick brush-textured hand-drawn theme title. The text may be tilted, offset, and partially overlapping, forming highly recognizable graphic text blocks, surrounded by small decorative patterns.

The right side, about 60%, is the main visual storytelling zone, featuring a large circular viewfinder window occupying about 70% of the frame's height, with a thick white border and dark hand-drawn outline. Inside the circle, a high-definition realistic photographic scene related to [Theme] is shown, with real spatial depth, natural light and shadow, and rich environmental details.

Arrange 5–8 cartoon sticker elements around the circular window, including [Character], theme props, environmental symbols, plants, animals, vehicles, or other related objects. Elements vary in size and overlap one another; some objects cross the circular border, while others extend from the edges of the frame toward the center, creating foreground, middle-ground, and background spatial relationships. Characters are placed at the lower left, above, or on either side of the circular window, performing interactive actions related to the theme. Props form an irregular C-shape or ring-shaped visual path around the circular window; top elements gather inward, and bottom elements carry the visual weight.

Composition details:
The oversized headline and the circular main visual form a dual focal point, with characters and props connecting the two visual zones. Partial occlusion, out-of-bounds cropping, asymmetrical balance, scale contrast, interlocking outlines, and sticker-style layering. Small sparkles, dots, short lines, and geometric shapes fill visual gaps.

Mixed media:
2D hand-drawn cartoon periphery × real photography inside the circular window. The realistic scene keeps the lighting, materials, depth of field, and spatial scale of real photography; the cartoon elements keep uniform thick outlines, flat fills, and organic contours.

Overall effect:
High information density, clear visual hierarchy, a relaxed, fun, lively internet commercial illustration. Strong theme recognition, unified colors, and a complete event key-visual design feel.

Horizontal 16:9, with a tiny signature voxcat naturally integrated into the bottom-right corner.
