Bottled Sleep Manga Cover

Create a vertical manga cover poster for a dark fantasy drama titled {argument name="main title text" default="眠気屋の小瓶"}, with the subtitle {argument name="subtitle text" default="眠気を売りすぎた漫画家"}. The composition shows a tired young male manga artist, {argument name="character name" default="Ren Mashima"}, seated at a cluttered drawing desk late at night inside a mysterious antique shop or studio. He has messy black hair, pale skin, sharp exhausted eyes, and wears a loose black button-up shirt. His left elbow rests on the desk with his hand against his temple, while his right hand reaches forward toward the viewer, holding a small corked glass bottle wrapped with thin metal wire and a paper tag bearing a crescent moon symbol. Inside the bottle is glowing blue-violet magical mist shaped like sleepy stardust, with tiny stars and a crescent moon, spilling faint smoke upward. The desk is covered with manga manuscript pages, ink pens, nibs, brushes, black ink bottles, a dark coffee mug, crumpled paper, and scattered art tools. Behind him, shelves hold many glass bottles and jars filled with dim blue, amber, and purple light, suggesting a shop that sells bottled sleepiness. A large window on the left reveals a deep blue night cityscape with stars and distant lit buildings. Use dramatic cinematic lighting: cool moonlight from the window, warm amber lamp highlights from the shelves, and bright magical blue glow from the bottle illuminating his fingers and face. Place the large ornate Japanese title across the top in elegant glowing white calligraphy with thin decorative swashes and a tiny bottle icon near the final character; place the smaller subtitle centered beneath it with thin horizontal divider lines and a small ornamental flourish. Style: highly detailed modern seinen manga cover illustration, painterly anime realism, intricate linework, moody noir atmosphere, glossy magical highlights, sharp focus on the character and bottle, dark indigo and gold palette. Canvas: vertical 9:16 cover, no border, no watermark, keep the title readable and dominant.
