微写实眼部肖像纹身

微写实纹身设计，展示单只人眼的极近距特写，在约4cm宽的小尺寸下呈现照片级细节。虹膜为丰富的榛色，以琥珀、青铜和橄榄色调的放射状纤维状纹路。瞳孔为深黑色椭圆，在两点钟位置有清晰的镜面白点高光。上眼睑在虹膜上方投下柔和阴影。精细的单根睫毛从两侧眼睑伸出——每根睫毛以单一精准墨线呈现，带有自然卷曲。眼下皮肤显示微妙毛孔质感和一条几乎不可见的毛细血管。周围皮肤渐变为裸色皮肤色调，无硬边界。纹身设计以1:1比例展示于白色参考卡片上，一边有毫米刻度。色调：黑色、暖灰和榛色琥珀——无彩色。

A micro-realism tattoo design showing a single human eye in extreme close-up, rendered with photographic-level detail at a small scale of approximately 4 cm wide. The iris is rich hazel with radiating fiber-like striations in amber, bronze, and olive tones. The pupil is a deep black ellipse with a crisp specular white dot highlight at the two-o'clock position. The upper eyelid casts a soft shadow across the upper iris. Fine individual lash hairs emerge from both lids — each lash rendered as a single precise ink stroke with natural curl. The under-eye skin shows a subtle pore texture and one barely visible capillary. The surrounding skin fades to bare skin tone with no hard border. The tattoo design is shown at 1:1 scale on a white reference card with millimetre markings along one edge. Palette: black, warm gray, and hazel-amber — no color.
