Draw a simple hand-drawn doodle of the attached photo, as if it were sketched by a person using a black marker. Use natural marker strokes, slightly wobbly outlines, subtle hand-drawn imperfections, slightly open line endings, and create a warm editorial doodle aesthetic. Avoid clean vector-style graphics and overly polished digital perfection. Keep the illustration simple, airy, flat, and understated. Use sky blue only as an accent color.

根据所附照片，画一幅简单的手绘涂鸦，仿佛是一个人用黑色马克笔随手勾勒的。使用自然的马克笔笔触，线条轮廓略带轻微抖动，加入微妙的手绘不完美感，线条末端略微未闭合，营造温暖编辑风格的涂鸦美感。避免干净矢量风格的图形和过度精致的数字完美感。保持插画简洁、通透、平淡而克制。仅以天蓝色作为点缀色。
