Subject: A translucent streamlined blue whale constructed from glowing blue lines, with tiny blue fluorescent particles drifting around its body. Scene: A night coastal scene, with a calm and vast dark blue sea in the foreground, a modern city skyline lit with warm lights standing on the distant coastline, city lights reflecting on the sea, and a deep night sky dotted with tiny stars above. Style: Futuristic tech aesthetic, fluid line art, dreamy and ethereal digital illustration style, with a high-end business texture. Color palette: The overall main tone is a deep, low-saturation dark blue, paired with the bright icy blue glowing effect of the whale, and accented with the warm yellow city lights as a contrasting color; the tone is cool, high-end, and harmoniously unified. Lighting: The whale emits a soft cool blue halo, with gentle and natural light edges, the city's warm light forms blurry reflection spots on the sea, the overall environment is dim, focusing the visual attention on the glowing whale, creating a quiet and soft lighting atmosphere. Composition: Horizontal wide-format composition, with the visual focus placed on the glowing whale at the right side of the frame, the sea and city skyline on the left balancing the frame's weight, the sea, city, and night sky naturally forming three visual layers, with ample negative space, resulting in an expansive and atmospheric visual effect.
