Concierto de Idol Anime en Acuarela

A luminous watercolor anime idol concert illustration of [Tachibana Kohaku], a single young female singer centered on stage, depicted from mid-thigh up in a dynamic three-quarter pose. She has [short soft blonde hair] adorned with a blue-and-white flower ornament and ribbon on one side, pale skin, sparkling gray-blue eyes, and a warm, emotional smile. She wears a white and pale-blue frilled idol dress featuring a fitted corset bodice with gold crisscross lacing, a blue floral neck accent, off-shoulder ribbon straps, layered ruffled skirt panels, and delicate wrist frills. Her right hand holds a single black handheld microphone near her mouth, while her left arm reaches toward the viewer with an open palm in a heartfelt gesture. The background depicts a concert venue filled with misty blue-violet washes, star-shaped sparkles, floating confetti, and five bright overhead spotlights casting visible white light beams downward. At the bottom edge, dark audience silhouettes hold glowing blue-white light sticks, softly blurred to create depth. Rendered in a transparent hand-painted watercolor style with visible paper texture, fluid washes, soft bleeding pigments, luminous white highlights, and expressive splatter effects. Color palette: [icy white, sky blue, lavender, and pale gold]. Vertical composition, emotional and radiant atmosphere, no text, no watermarks.
