Nostalgic Lo-Fi Art Style

Convert this illustration with Authentic Lo-Fi Art Style. Add warm, slightly muted pastel tones, film grain, soft focus, light fading, and vignette to strongly express a nostalgic and chilly atmosphere. Soft natural light gently envelops the character, casting warm light and shadow on skin and hair. Finish the entire look with a relaxed, calm, nostalgic, and pleasant Lo-Fi mood. Completely preserve the original composition and character.
