A photorealistic cinematic scene inspired by Japanese period dramas. A realistic marmot dressed as a traditional samurai with a chonmage hairstyle and a kimono, riding a majestic white horse galloping along a sunlit beach at dawn. The scene evokes the style of classic samurai TV openings, with dramatic camera angles, flying sand, and glistening ocean waves. The marmot’s expression is noble and determined, as if he were the hero of an epic story. The lighting is golden and warm, emphasizing movement and atmosphere. In the bottom right corner, add the English title “The Horse Riding Instructor” written in bold red brushstroke-style letters, resembling traditional Japanese calligraphy. Hyper-realistic details, dynamic motion blur, cinematic composition, warm tone.
