波光粼粼的蓝色鱼群

目标：创作一幅高度精细的纵向海洋插画，描绘拥挤的鱼群，呈现出如洁白背景上闪烁的水彩与水墨海报般的效果。 画布：纵向构图，2:3 比例，满版设计，无边框。在鱼群之间留出细小的白色间隙，并在右下角添加微小的日期和艺术家签名。 主体细节：总共展示 55 条鱼：5 条大型特征鱼和 50 条小型饵鱼。5 条大型鱼包括：1 条位于顶部、背鳍高耸且拥有金色大眼的巨大蓝色金枪鱼状鱼，右侧边缘略有裁剪；1 条位于中左侧、吻部尖锐且牙齿可见的银蓝色梭鱼状掠食者；1 条位于中右侧、拥有金色眼睛和粉红色鳍的粉红色鲷鱼状鱼；1 条位于中下部、拥有黑色圆眼和浅色腹部的深蓝色金枪鱼状鱼；1 条位于下部、下颚锋利且牙齿可见的银蓝色梭鱼状掠食者。50 条小型鱼为细长的沙丁鱼或鲭鱼形状，大多水平向左或向右游动，密集分布在大型鱼之间及周围，部分在边缘处略有裁剪。 视觉风格：精致的水彩插画与细腻的钢笔水墨线条相结合，明亮的反光鳞片呈现为数百个圆形亮片状圆点，带有金属光泽，鱼类解剖轮廓清晰，鱼鳍透明，眼睛细节丰富，并带有层叠的蓝色阴影。使用以 {argument name="main color palette" default="钴蓝色、群青色、冰白色、银色和浅青色"} 为主的明亮海洋色调，并配有一条 {argument name="accent fish color" default="粉红色、珊瑚红和暖金色"} 的对比色鱼。整体感觉应清新、夏日、湿润且明亮，如同装饰性的 AI 艺术画作。 文字内容：在右下角，添加微小的印刷日期 {argument name="date text" default="2026 年 7 月 11 日"} 和精致的手写签名 {argument name="signature" default="Oyagi"}。保持文字微小且不突兀。 约束条件：无人物，无风景，无水面，无气泡，无边框，无额外排版。保持鱼群的密集层叠，但确保每条鱼在白色负空间中都有清晰的轮廓。

Goal: Create a highly detailed vertical marine illustration of a crowded school of fish, like a shimmering watercolor-and-ink poster on a clean white background. Canvas: Portrait orientation, 2:3 ratio, edge-to-edge composition with no frame. Leave small white gaps between fish, and add a tiny date and artist signature in the bottom-right corner. Subject details: Show exactly 55 fish total: 5 large feature fish and 50 smaller baitfish. The 5 large fish are: 1 huge blue tuna-like fish across the top with a tall dorsal fin and large golden eye, partially cropped at the right edge; 1 long silver-and-blue barracuda-like predator across the middle-left with pointed snout and visible teeth; 1 pink-red snapper-like fish on the right-center with golden eye and rosy fins; 1 large deep-blue tuna-like fish across the lower middle with round black eye and pale belly; 1 long silver-blue barracuda-like predator along the lower section with sharp jaw and teeth. The 50 smaller fish are slim sardine or mackerel shapes, mostly swimming horizontally left-to-right or right-to-left, distributed densely between and around the larger fish, with a few partially cropped at the edges. Visual style: Intricate watercolor illustration mixed with fine pen-and-ink linework, bright reflective scales rendered as hundreds of circular sequin-like dots, metallic sparkle, crisp anatomical fish outlines, transparent fins, detailed eyes, and layered blue shadows. Use a luminous ocean palette dominated by {argument name="main color palette" default="cobalt blue, ultramarine, icy white, silver, and pale cyan"}, with one contrasting fish in {argument name="accent fish color" default="pink, coral red, and warm gold"}. The overall feeling should be refreshing, summery, humid, and bright, like a decorative AI art print. Text content: In the bottom-right corner, add the small printed date {argument name="date text" default="July 11, 2026"} and a delicate handwritten signature {argument name="signature" default="Oyagi"}. Keep the text tiny and unobtrusive. Constraints: No humans, no scenery, no water surface, no bubbles, no border, no extra typography. Maintain dense fish layering but keep every fish clearly outlined against white negative space.
