生成一张 9:16 竖版、高精度 3D CG 双人角色插画。
整体风格为 高级二次元 3D CG 渲染，画面精致、通透、明亮，具有高完成度游戏角色宣传图 / 商业级角色海报质感。整体气质梦幻、浪漫、暧昧、克制、甜蜜，带有明显象征爱情的柔光氛围与高传播感。
画面主体为两位成年东方幻想系女性角色，位于巨大明亮的落地窗边。构图采用半身到大腿的近景视角，镜头略带低机位仰拍，增强画面的压迫感、张力与视觉冲击力。整体为明显的对角线构图 + S 型双人互动构图，人物身体紧密交叠，视觉焦点集中在两人极近的面部距离与上半身曲线关系。
左侧角色：
成年女性，银白色短发，发丝轻盈蓬松，发尾略带自然卷度，头侧佩戴黑色花朵发饰，并搭配细长的红黑飘带。眼睛为淡红色，五官精致柔和，神情温柔、主动，带有轻微侵略感。她是主动贴近的一方，身体明显前倾，向右侧角色压近，一只手臂环过对方肩颈或撑在对方身侧，另一只手贴近对方腰侧或背后，形成明显的壁咚式逼近感。
右侧角色：
成年女性，鲜红色长发，高马尾造型，发丝浓密顺滑，在逆光中轻微飞扬。眼睛为红琥珀色，五官成熟精致，神情从容、自信、温柔，带一点被逼近时的轻微挑衅感。她轻靠在黑色窗框边缘，背部和肩部贴近窗边，身体微微后仰，腰胯自然扭转，站姿具有明显柔美 S 曲线。
两位角色都拥有成熟、丰腴、饱满、自然协调的女性体态。胸部饱满圆润，腰部收束清晰，腰臀过渡流畅，大腿和手臂带有适度柔软肉感，整体曲线明显但优雅克制，不低俗。
两人关系极其亲密：鼻尖几乎相触，嘴唇距离很近，眼神近距离暧昧对视，形成强烈的贴近感、压迫感、亲密感与欲言又止的情绪张力。不是普通拥抱，也不是普通合照，而是明显的“主动逼近 + 被压在窗边”的窗边亲密构图。
两人穿着统一风格的白色幻想风改良短礼裙，整体为高级时装感与轻幻想感结合。服装包含：白色主色调、轻盈吊带、露肩设计、收腰剪裁、侧腰镂空、黑色细带交叉结构、少量红色点缀、丝缎与轻薄纱质混合材质、裙摆轻盈自然展开。服装自然衬托人物丰腴饱满的身体曲线，突出胸腰臀比例与女性轮廓，整体优雅、梦幻、精致，不透明，不过度暴露。
场景位于室内巨大落地窗边，窗外强烈自然光照入，形成高级逆光效果。整体光线偏温暖的金粉色 / 蜜桃粉色夕阳柔光，带有象征爱情的甜蜜氛围。人物边缘有柔和发光轮廓光，空气中漂浮少量红色花瓣、细小光点、微尘粒子和淡淡的心形散景光斑，营造浪漫恋爱氛围。发丝与飘带随空气轻微摆动，增强动态感。背景简洁、干净、明亮，不要复杂家具和杂乱信息。

Generate a 9:16 vertical, high-precision 3D CG double-character illustration.
The overall style is high-end anime 3D CG rendering, with a refined, transparent, and bright screen, possessing the texture of high-completion game character promotional images / commercial-grade character posters. The overall temperament is dreamy, romantic, ambiguous, restrained, and sweet, with a distinct soft-light atmosphere symbolizing love and high shareability.
The main subjects are two adult Oriental fantasy-style female characters, located by a huge bright floor-to-ceiling window. The composition uses a close-up perspective from the upper body to the thighs, with a slightly low-angle shot to enhance the pressure, tension, and visual impact of the image. The overall composition is a clear diagonal + S-shaped double-person interaction composition, with the characters' bodies closely overlapping, and the visual focus concentrated on the extremely close facial distance and upper body curve relationship between the two.
Left character:
Adult female, silver-white short hair, light and fluffy strands, slightly naturally curled at the ends, wearing black flower hair accessories on the side of the head, paired with slender red and black streamers. Eyes are light red, features are exquisite and soft, expression is gentle and active, with a slight sense of aggression. She is the side actively drawing closer, her body leaning forward significantly, pressing towards the right character, with one arm around the other's shoulder/neck or propped beside the other, and the other hand close to the other's waist or back, creating a clear kabedon-style approach.
Right character:
Adult female, bright red long hair, high ponytail hairstyle, dense and smooth hair strands, flying slightly in the backlight. Eyes are red-amber, features are mature and exquisite, expression is calm, confident, and gentle, with a slight sense of provocation when being approached. She leans lightly against the edge of a black window frame, with her back and shoulders close to the window, her body leaning back slightly, waist and hips naturally twisted, the standing posture has a clear beautiful S-curve.
Both characters have mature, plump, full, naturally coordinated female physiques. Full and rounded breasts, clearly cinched waist, smooth waist-to-hip transition, thighs and arms with appropriate soft fleshiness, overall curves are obvious but elegant and restrained, not vulgar.
The relationship between the two is extremely intimate: noses almost touching, lips very close, eyes meeting in an ambiguous close-range gaze, forming a strong sense of closeness, pressure, intimacy, and wordless emotional tension. Not a normal hug, not a normal group photo, but a clear "active approach + pressed against the window" intimate window composition.
Both wear a unified style of white fantasy-style modified short formal dresses, overall a combination of high-fashion sense and light fantasy. The clothing includes: white main color, light suspenders, off-the-shoulder design, waist-cinching cut, side-腰镂空 (waist cutouts), black thin strap cross structure, a small amount of red accents, mixed materials of silk satin and thin gauze, skirt hem naturally spreading lightly. The clothing naturally sets off the characters' plump and full body curves, highlighting the chest-waist-hip ratio and female silhouette, overall elegant, dreamy, exquisite, non-transparent, not overly exposed.
The scene is located by a huge indoor floor-to-ceiling window, with strong natural light shining in from outside, forming a high-end backlighting effect. The overall light is a warm golden-pink / peach-pink sunset soft light, with a sweet atmosphere symbolizing love. There is a soft glowing rim light on the edges of the characters, a few red petals, small light spots, fine dust particles, and faint heart-shaped bokeh spots floating in the air, creating a romantic love atmosphere. Hair strands and streamers sway slightly with the air, enhancing the sense of movement. The background is simple, clean, and bright, without complex furniture or cluttered information.
Image texture requirements:
3D CG high-precision rendering, PBR materials, exquisite facial modeling, delicate skin texture, realistic subsurface scattering, soft highlights, clear hair strand details, realistic fabric folds, cinematic lighting, shallow depth of field, commercial poster grade completion, the overall presentation is high-end, dreamy, ambiguous, sweet, restrained, high-tension, and highly shareable visual effects.
Negative prompts:
No normal hugs, no two people standing parallel, no stiff movements, no characters too far apart, no unbalanced body proportions, no too thin, no flat chest, no unobvious curves, no deformed fingers, no multiple hands or arms, no broken face, no low resolution, no cheap flat-painted anime, no realistic photo style, no vulgar eroticism, no transparent clothing, no nudity, no underage feeling, no cluttered background, no watermark, no text, no signature.
