YouTube Thumbnail - Anime Skywork MV Thumbnail

Goal: Create a bright anime YouTube thumbnail / promotional banner for a music-video-making tutorial, with a cute idol mascot on the right and bold Japanese headline typography on the left. Canvas: Wide 16:9 horizontal banner, approximately 1200×675 px. High-energy composition with no empty space, suitable for social media and YouTube promotion. Layout: Left half is dominated by large stacked headline text with thick outlines and drop shadows. Right half shows exactly 1 anime idol girl in close-up from chest up, facing the viewer, mouth open in an excited singing expression. Bottom-left contains exactly 1 white rounded rectangle brand badge with the Skywork logo icon and the word “Skywork.” Text content: Use exactly 3 main Japanese headline blocks: 1) top small headline {argument name="top headline text" default="音楽情報入れたら"}, 2) central oversized headline {argument name="main headline text" default="MVが完成した!"}, 3) bottom subtitle {argument name="subtitle text" default="Skywork Video 1つで完結!"}. Make the central “MV” especially huge, bright red with white and dark navy outlines; make the rest of the central headline yellow-gold with red and dark outlines. Keep the typography bold, rounded, pop-style, slightly tilted, with strong white stroke and dark red/navy shadow for readability. Subject details: The character is {argument name="character name" default="Mona"}, a cheerful kawaii anime idol girl with long brown twin tails, amber-orange sparkling eyes, flushed cheeks, and glossy highlights. She wears a white and lavender frilly idol outfit with a high collar, bare shoulders, purple trim, gold star ornaments, and large lavender bows in her hair. She holds exactly 1 magical idol wand near the right edge: gold handle, circular gold frame, purple faceted star gem in the center, small angel wings, ribbons, crescent moon, and star charms. Visible accessories should include exactly 2 large lavender hair bows, 1 gold crescent moon hair ornament, multiple small gold star clips, 1 star choker ornament, and the single wand. Background and effects: Use a vivid pink, purple, orange, and gold concert-light background with diagonal speed lines, bokeh, confetti, sparkles, and glow effects. Add exactly 1 white music note icon floating above the character’s head. Scatter many small star-shaped sparkles around the text and character. Overall mood is celebratory, cute, magical idol, and energetic. Visual style: Polished modern Japanese anime illustration, glossy eyes, soft cel shading, clean line art, saturated colors, strong rim lighting, high contrast, crisp thumbnail readability, commercial PR banner style. Constraints: Keep all important text fully legible and inside the safe area. Do not add extra characters, extra logos, watermarks, QR codes, or additional text beyond the specified headline and Skywork badge.
