Banner promocional para curso de diseño de e-commerce

Horizontal promotional banner for an e-commerce visual design course, rendered in a cheerful 3D cartoon commercial illustration style. Composition & Layout: Central glowing circular orange sunburst badge radiating rings and soft light rays. Overlaid in the exact center is the main course headline in two stacked lines: top line reads "[GPT-Image2]", bottom line reads "[电商视觉大片实战课]". The typography is extra-large, bold rounded 3D display lettering with white face, red-orange extruded shadow, thick orange outline, and a subtle warm glow. Setting & Elements: A stylized shopping mall corridor or retail street recedes symmetrically toward the glowing center along a tiled walkway. On the left: retail shelves holding 2 cosmetic bottles, 4 branded shopping bags, 2 small floating orange bags, and a potted plant near the walkway. On the right: analytics dashboard screens (a pie chart at the top, a line-and-bar graph at mid-height, and a metric card below) along with display plinths and gift boxes. Lower-right foreground features a wire shopping cart filled with orange product boxes and gold coins. Three floating app icons float above the headline (a blue cloud upload icon, an orange checkmark badge, and a red wallet icon), surrounded by 5 scattered gold coins, confetti ribbons, and soft floating clouds against distant blue city silhouettes. Lighting & Color: Vibrant warm orange, yellow, and red palette contrasted with cool sky-blue accents and crisp white highlights. Soft ambient occlusion, glossy plastic textures, clean edges, playful isometric depth. Constraints: Perfectly centered, highly legible text. Balanced framing around the typography. No human figures, no faces, no watermarks, no QR codes.
