A grand vertical anime-realism cover illustration of Furina from Genshin Impact on an opulent Fontaine opera stage. One girl, faithful recognizable Furina with pale silver-white hair accented by blue, vivid blue eyes, her small dark top hat and ornate navy, white and gold theatrical outfit. She stands at center stage in a graceful confident pose, one hand extended toward the viewer as ribbons of clear water arc around her like a spotlighted curtain. Full-body composition with her face still crisp and prominent, natural proportions and elegant movement in the coat tails and hair. Deep blue velvet curtains, gilded architecture and a glossy stage floor create a luxurious background, while cool aqua highlights and warm theatrical spotlights produce sparkling reflections and restrained bokeh. The finish blends precise anime character design with realistic skin, hair, embroidered fabric, metal trim, water droplets and cinematic lighting. Premium promotional key visual, dramatic centered silhouette, no audience, no readable text, no logos, no watermark.
