Art style: манга 4.
Remaja laki-laki berdiri membungkuk di atas ruang mesin, memegang kunci inggris dengan erat. Matanya menatap tajam ke arah komponen mesin dengan fokus yang sangat dalam. Keringat menetes di dahinya yang kotor. Pencahayaan kontras tinggi dengan palet warna biru tua dan jingga metalik menciptakan suasana penuh dedikasi.

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image entirely in "манга 4" style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "манга 4".
Keep the subject, composition, camera angle, lighting direction, and colour palette from the description above — but EVERY surface, skin, fabric, material, and environmental element must be rendered in the "манга 4" idiom, not in any other medium.
