Book cover illustration, vertical format, featuring a young cowboy (Troy, 18 years old, blonde hair, blue eyes) standing next to an older, intellectual-looking man (the teacher, late 20s, with glasses, holding a few books). Troy is wearing classic cowboy attire and is gently touching a horse. The teacher is casually dressed, with a warm and thoughtful demeanor. The background shows a ranch with a fence, open fields, and several horses grazing under a golden sunset. No text or typography at the bottom, cinematic lighting, warm tones, realistic style. --s 50
