Ultra cinematic 15-second tennis commercial for a major international tennis tournament 2026. Hand-drawn ink-and-marker illustration aesthetic mixed with dynamic modern sports animation. Deep navy shadows, saturated clay orange courts, rough sketch textures, imperfect pen strokes, paper grain, energetic scribble motion lines. Every frame feels like an animated editorial sports illustration brought to life. Includes a full 0:00 to 0:15 shot flow with VFX, SFX, music direction, style references, and negative style constraints (not anime, not Pixar, not clean vector art).
