Gothic Anime Bassist Story Screen Prompt

Create a vertical smartphone screenshot-style anime illustration of a dark, moody live-concert scene. The main subject is one androgynous young male bassist, {argument name="character name" default="SUGO"}, shown from thighs to head in a dramatic three-quarter close-up, looking downward with a serious, melancholic expression. He has extremely voluminous messy {argument name="hair color" default="black"} hair with blue-white highlights, long bangs falling over one eye, pale skin, sharp narrow eyes, a slim face, and a small black stud earring. Dress him in an all-black gothic rock outfit: black high-neck shirt, loose black jacket, leather harness straps, multiple silver chain necklaces, bracelets, rings, and dangling waist chains. He holds exactly one glossy black electric bass guitar angled diagonally from lower left to upper right, with exactly five visible strings; his right hand plucks near the body and his left hand grips the fretboard. The background is a dark concert stage with blurred drum kit elements, haze, floating dust or confetti specks, and exactly four bright cool-white stage spotlights creating strong rim light and cinematic blue highlights. Add a handwritten white signature-style message near the lower right of the illustration reading {argument name="handwritten message" default="thank you for SUGO"}. Frame the artwork inside a black mobile app viewer UI: a top black bar with exactly four visible UI elements — a back chevron on the left, centered white title text {argument name="top bar text" default="thank you for 8... 😈"}, one list/menu icon, and one share/refresh arrow icon on the right. At the bottom, include a black navigation area with exactly two white carousel chevrons centered over the image, one left and one right, plus one thin white iPhone home indicator bar at the very bottom. Style: highly polished Japanese anime / otome game key visual, glossy rendering, high contrast, dramatic lighting, detailed hair strands, elegant rock idol atmosphere, no extra characters, no extra text, no watermark.
