Watercolor Idol Concert Performance

Create a luminous watercolor anime idol concert illustration of {argument name="character name" default="Tachibana Kohaku"}, a single young female singer centered on stage, shown from mid-thigh up in a dynamic three-quarter pose. She has {argument name="hair color" default="short soft blonde hair"} with a blue-and-white flower hair 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 with exactly 5 main outfit features: 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 exactly 1 black handheld microphone near her mouth, while her left arm reaches toward the viewer with an open palm, creating a heartfelt invitation. The background is a dazzling concert venue filled with misty blue-violet washes, star-shaped sparkles, confetti, and exactly 5 bright overhead spotlights casting visible white beams down from the top of the image. At the bottom edge, include dark audience silhouettes and glowing blue-white concert light sticks, slightly blurred and cropped to emphasize depth. Use a transparent, hand-painted watercolor style with visible brushstrokes, paper texture, soft bleeding pigments, layered washes, luminous whites, and expressive splatter effects to convey radiant light. Color palette: {argument name="main color palette" default="icy white, sky blue, lavender, and pale gold"}. Composition should feel hopeful, emotional, and radiant, like a magical idol performance capturing the idea of light returning. Vertical portrait canvas, high detail, no text, no watermark, no logo, no photorealism.
