VTuber Çıkış Duyuru Afişi

Using the provided reference image as the character design base, transform the character into a polished VTuber debut announcement poster while preserving the character design, [hoodie, headphones, choker, star and constellation motifs, and overall purple-blue night palette]. Dramatic upper-body key visual of the character seated at a streaming desk, one hand near the face, inside a cozy nighttime bedroom studio. In the background, a window overlooks a starry night city with soft curtains, hanging star ornaments, glowing computer monitors, a desk microphone, keyboard or game controller, and a drink mug. Soft cinematic lighting with sparkly atmospheric particles. Styled as an official Japanese VTuber debut teaser poster and social media promo visual. Include dense decorative typography and framed info panels: a prominent title with the Japanese name and romanized text "[Yume Asta]", a short poetic tagline, 4 boxed profile cards labeled "Profile", "Like", "Keyword", and "配信スタイル", plus 1 smaller boxed hashtag community section at the bottom-left. A large glowing headline at the bottom center reads "VTuber Debut" and "Coming Soon", with a ribbon-style banner underneath containing Japanese debut announcement text.
