Japanese Marketing Course Thumbnail AI Image Prompt

Create a vibrant Japanese marketing course thumbnail for {argument name="campaign topic" default="CM・広告・商品訴求"}. Use a 16:9 horizontal canvas, 1184×768 style, with a glossy purple-blue neon aesthetic and soft depth-of-field office lighting. Background: a modern cosmetics marketing workspace with a blurred large monitor showing a campaign dashboard; visible English text on the monitor includes “NEW CAMPAIGN” and small chart/product panels. On the right, place a young woman marketer in a lavender blouse, seated at a desk with one hand near her chin holding a pen; her face is intentionally hidden by a large opaque matte brown rectangle. Desk details include exactly 5 main objects: an open laptop on the left, a disposable coffee cup in front, printed marketing sheets with colorful layout thumbnails, cosmetics bottles on the right, and a small sign reading “NEW ARRIVAL 30% OFF LIMITED CAMPAIGN.” Overlay a large rounded gradient banner across the lower-left to center, blue-to-purple with glow and transparency. On the far left of the banner, put a large circular badge with the white text “2.”. Main Japanese headline on the banner: “CM・広告・商品訴求” in bold white rounded sans-serif, with “商品訴求” on the second line. Beneath it, add a white pill-shaped label with blue and pink text: “商品訴求・販促・告知向け”. Add exactly 3 large neon line icons: a cyan megaphone in the upper left, a pink shopping bag below it, and a purple play button inside a rounded rectangle on the upper right. Add exactly 8 small glowing sparkle accents scattered around the composition, plus a small pink upward bar-chart icon near the bottom center. Overall style: Japanese YouTube thumbnail, polished digital advertising design, luminous gradients, cinematic blur, clean readable typography, no watermark, no extra text beyond the specified labels.
