Lo-Fi 艺术风格转换

Please transform this illustration into a {argument name="style" default="professional Lo-Fi art style"}. Add warm, slightly muted pastel tones, film grain, soft focus, light fading, and a vignette to strongly express a nostalgic and chill atmosphere. Let soft natural light gently envelop the character, casting warm highlights and shadows on the skin and hair. Finish with the overall relaxed, somewhat nostalgic, and comfortable mood unique to Lo-Fi. Completely maintain the original composition and character.
