Hybrid Cartoon Photo Event Banner

{argument name="theme" default="Summer Music Festival"}, {argument name="character" default="Cute Mascot"}, Contemporary trendy cartoon illustration x Cartoon Graffiti x Sticker Art x playful editorial illustration x Neo-retro American cartoon x Commercial Event Key Visual design.

Visual Style:
Thick dark brown hand-drawn outer contours, uneven line thickness, rounded exaggerated cartoon shapes, irregular organic geometric color blocks, flat vector coloring, slight hand-drawn texture. Characters feature exaggerated head-to-body ratios, simplified facial features, fun expressions, and rhythmic actions. High-saturation contrasting colors, randomly designing 3-5 main colors based on the theme, large areas of solid color fields, clear warm/cool and brightness contrast.

Core Composition:
Horizontal commercial banner, asymmetric left-right zoning, overall dense surround-style collage composition.

Left side approx. 40% is the visual title area, featuring huge, irregular, thick brush-stroke style hand-drawn theme titles. Text can be tilted, offset, partially overlapping, forming highly recognizable graphical text blocks, surrounded by small decorative patterns.

Right side approx. 60% is the main visual narrative area, with a large circular viewfinder window occupying about 70% of the image height, using a thick white border and dark hand-drawn outer contour. Inside the circle is a high-definition realistic photographic scene related to the [theme], with real spatial depth, natural light and shadow, and rich environmental details.

Around the circular window, arrange 5-8 cartoon sticker elements, including [characters], theme props, environmental symbols, plants, animals, vehicles, or other related objects. Elements vary in size, interpenetrate each other, some crossing the circular border, some extending from the edges toward the center, creating foreground, midground, and background spatial relationships.

Characters are distributed at the bottom-left, top, or sides of the circular window, performing interactive actions related to the theme. Props form an irregular C-shape or ring visual path around the circular window, with top elements gathering inward and bottom elements bearing visual weight.

Composition Details:
The oversized title and circular main visual form dual focal points, connecting people and props between two visual areas. Partial occlusion, boundary cropping, asymmetric balance, size proportion contrast, contour intersection, sticker-style layering. Small starbursts, dots, short lines, and geometric shapes fill visual gaps.

Mixed Media:
2D hand-drawn cartoon periphery x Realistic photography inside the circular window. The realistic scene maintains real photography lighting, materials, depth of field, and spatial scale; cartoon elements maintain unified thick outlines, flat coloring, and organic contours.

Overall Effect:
High information density, clear visual hierarchy, relaxed, interesting, lively internet commercial illustration. Distinctive theme recognition, unified colors, complete event key visual design feel.

Landscape 16:9, extremely small signature voxcat naturally integrated in the bottom right corner.
