Art style: Cinematic Realistic.
A modern, luxurious office with a large window overlooking a city skyline at dusk. John stands in the center of the room, facing the camera with a confident smile. He is holding a large, black, rectangular sign with both hands. The sign has the text 'Made with DOITONG' and 'Available for iOS' written on it in clean, white font. Photorealistic, cinematic lighting, sharp focus on the character and the sign.

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image entirely in "Cinematic Realistic" style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "Cinematic Realistic". 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 "Cinematic Realistic" idiom, not in any other medium.
