ปรับแต่งเส้นภาพวาดตัวละครอนิเมะ

Maintain the exact art style, character design, colors, rendering, and overall visual quality of the reference image, modifying only the line art of the character. Refine and correct the line art around [the girl's facial features and hair strands], smoothing contours and fixing imperfections. Keep any additions subtle and minimal, matching the delicate, thin, and soft line work of the original illustration.
