植物学家的亚麻领口头像

Head-and-shoulders portrait of a 50-year-old woman botanist with short silver-streaked hair and a plain linen collared shirt. Gentle Rembrandt light leaves a small triangle on the shadowed cheek, dark olive background, natural skin lines, direct thoughtful gaze.

50岁女性植物学家的头肩肖像，短发夹着银丝，穿素色亚麻翻领衬衫。柔和伦勃朗光在暗侧脸颊留下小三角亮区，深橄榄背景，皮肤纹理自然，目光直接而沉静。
