提示詞

建立一幅以天體鯨鯊為單一主體的數位插畫，將其孤立呈現在乾淨的白色背景上。鯨鯊以優雅的垂直弧線呈現，朝左上方游去；頭部大而圓，嘴巴微微張開，眼睛細小而平靜，寬闊的身體向下並向周圍彎曲，形成舒展的月牙形，尾巴位於左下方。正好加入 7 個可見的鰭：背部上方 1 個大型背鰭、1 個較小的後背鰭、2 個側面的胸鰭、沿著腹側分布的 2 個小型下腹鰭／臀鰭，以及 1 個寬大的月牙形尾鰭。讓這隻動物呈現平滑、半寫實的 3D 繪畫質感，具有柔和的明暗和富有光澤的皮膚，但將鯨鯊自然的斑紋替換為鮮明的銀河紋理：以飽和的鈷藍、紫羅蘭、洋紅、青色與溫暖的粉橘色星雲漸層構成，整個身體布滿無數細小的星點與明亮的星芒。頭部在吻部附近應散發較溫暖的粉紅與蜜桃色光芒，沿著身體逐漸過渡為藍色與紫色，腹部曲線上帶有綠松石色高光。保持輪廓優雅、奇幻而寧靜，不要有水、氣泡、景物，也不要在身體外加入裝飾性符號。在右下角加入一個小型藝術家簽名與日期，以低調的黑色手寫字體呈現，上方寫著 July 30, 2026，下方寫著 Oyagi。高解析度的方形至直幅構圖，柔和明亮的奇幻藝術風格，清晰邊緣，主體置中，大量白色留白。

Create a single-subject digital illustration of a celestial whale shark, isolated on a clean white background. The whale shark is shown in a graceful vertical arc, swimming upward toward the upper left with its head large and rounded, mouth slightly open, tiny calm eye, broad body curving down and around into a sweeping crescent shape, and tail at the lower left. Include exactly 7 visible fins: 1 large dorsal fin on the upper back, 1 smaller rear dorsal fin, 2 side pectoral fins, 2 small lower pelvic/anal fins along the underside, and 1 broad crescent tail fin. Give the animal a smooth semi-realistic 3D painterly form with soft shading and glossy skin, but replace natural whale-shark markings with a vivid galaxy texture: saturated cobalt blue, violet, magenta, cyan, and warm pink-orange nebula gradients, filled with countless tiny star speckles and bright starbursts across the entire body. The head should glow warmer pink and peach near the snout and transition into blue and purple along the body, with turquoise highlights on the belly curve. Keep the silhouette elegant, whimsical, and serene, with no water, no bubbles, no scenery, and no decorative symbols outside the body. Add a small artist signature and date in the bottom-right corner reading July 30, 2026 above Oyagi, in subtle black handwritten script. High-resolution square-to-portrait composition, soft luminous fantasy art, crisp edges, centered subject, ample white negative space.
