柔和彩虹色 3D 女孩半身像
一款柔和的 3D 彩虹色女孩半身肖像，风格可爱且极具艺术感，适合用于奇幻角色设计或个人头像。
Create a clean 3D stylized bust portrait of a cute young girl with soft toy-like clay material, centered on a white background. The character has a large rounded head, small delicate nose, gentle closed-mouth smile, smooth cheeks, and large simplified almond-shaped eyes with no visible pupils, glowing with a pastel gradient. Give her long thick wavy hair with a sweeping side part and sculpted ribbon-like curls framing the face; the hair falls behind her shoulders in broad soft waves. She wears a simple sleeveless top with a rounded neckline and rounded shoulders, shown from upper torso upward as a bust sculpture. Use an iridescent rainbow pastel color palette blending cyan, turquoise, violet, lavender, pink, peach, orange, mint, and soft yellow across the entire figure, with smooth gradients and subsurface-scattering softness. Lighting should be bright, diffused, and studio-clean, creating a glossy matte-plastic/clay look with gentle highlights and minimal shadows. Composition is vertical portrait, three-quarter view facing slightly right, head and shoulders filling most of the frame, lots of clean white negative space around the figure. Add a small handwritten artist signature and date in the bottom-right corner reading {argument name="signature text" default="July 29, 2026 Oyagi"}. Keep the image text-free except for that signature, with no background objects, no hard outlines, no photorealistic skin texture, and no extra accessories.创作一张干净的 3D 风格化年轻女孩半身肖像，采用柔软的玩具质感粘土材质，主体居中于白色背景。角色拥有圆润的大头、精致的小鼻子、温柔的闭口微笑、光滑的脸颊，以及简化的大杏仁眼（无可见瞳孔），散发着柔和的彩虹渐变光泽。她留着浓密的长波浪卷发，侧分刘海，发丝呈丝带状雕塑感，环绕脸部，长发在肩后呈现出宽阔柔和的波浪。她穿着一件简单的圆领无袖上衣，画面展示从上半身开始的半身雕塑。整体采用虹彩般的彩虹色调，融合了青色、绿松石色、紫罗兰色、薰衣草色、粉色、桃色、橙色、薄荷绿和柔黄色，色彩过渡平滑，具有次表面散射的柔和感。光照应明亮、均匀且具备摄影棚级的干净感，呈现出光泽哑光塑料或粘土的质感，带有柔和的高光和极少的阴影。构图为竖向肖像，四分之三侧面视角，头部和肩部占据画面大部分空间，周围留有大量干净的白色负空间。在右下角添加一个小巧的手写艺术家签名和日期，内容为 {argument name="signature text" default="July 29, 2026 Oyagi"}。除该签名外，图像中不应包含任何文字，背景无杂物，无硬轮廓线，无写实皮肤纹理，且不添加额外配饰。
