Twin Idols Under Sakura Stars

Create a cinematic wide anime illustration of two futuristic schoolgirl idols seen from behind, holding hands while running or floating across a mirror-like shallow ocean at sunset beneath a vast starry sky. The left girl has {argument name="left character hair color" default="long pink twin-tail hair"}, a black oversized streetwear jacket with punk straps and graphic panels, a short pleated skirt, thigh straps, chunky lace-up platform sneakers, and large futuristic headphones with a bow-like accessory; she is backlit by a warm pink sunset and framed by dense cherry blossom branches on the far left. The right girl has {argument name="right character hair color" default="dark blue twin-tail hair"}, a white oversized jacket with black abstract patterns, a dark pleated skirt, thigh straps, chunky blue-and-white sneakers, and a large ribbon accessory in her hair; her side is lit by cool cyan moonlight and blue sky tones. Their arms stretch toward the center and their fingers interlace delicately, with petals and tiny light particles swirling around them. The background is split into a dramatic pink-to-blue gradient: warm rose sky and glowing low sun near the left horizon, transitioning into deep blue night sky with stars, nebula-like clouds, shooting stars, and a crescent moon on the right. The water surface reflects both figures, cherry blossoms, sunset colors, and blue sky with glossy ripples. Use a highly detailed Niji-style anime aesthetic, vibrant saturated colors, dynamic wide-angle composition, elegant linework, luminous rim lighting, dreamy magical atmosphere, intricate clothing details, flowing hair ribbons, and abundant sakura petals. Keep exactly two girls as the main subjects, viewed mostly from behind, no text, no watermark, no extra characters, high-resolution 16:9 landscape composition, polished gpt-image-2 anime refinement quality. Optional mood: {argument name="mood" default="bittersweet magical spring night"}.
