Mécanicien couvert de graisse avec moto vintage dans un diner néon

Hand-drawn ink illustration with colored pencil accents of a grease-smudged mechanic leaning against a vintage motorcycle inside a cozy neon-lit diner at midnight. Loose sketchy contour lines define their muscular arms and worn coveralls, sleeves rolled up, one button undone. Sepia base with muted teal on the bike and coral on their lips. Cross-hatching creates deep shadows. They wink at viewer, wrench in hand, playful doodle hearts floating nearby. Intimate retro atmosphere. Textured paper grain.
