Young gascon swordsman with pony on a french country road

Create a cinematic, highly detailed portrait of D'Artagnan as he first appears in Alexandre Dumas' The Three Musketeers. He is a lean, athletic young Gascon of about eighteen, with a long, sun-browned face, prominent cheekbones, an intelligent, determined gaze, and a finely chiseled hooked nose. He has dark brown hair beneath a black beret adorned with a single feather. He wears a faded blue woolen doublet, weathered from travel, a simple brown traveling cloak draped over his shoulders, sturdy leather boots, and a well-worn sword hanging at his side. His clothing is neat but clearly modest, reflecting a poor young nobleman setting out to seek his fortune. He stands confidently beside a small, scruffy yellow Béarn pony on a country road leading toward Paris, with rolling countryside in the background. The mood conveys youthful ambition, courage, and determination. Render the scene in a realistic, historical style inspired by 17th-century France, with natural lighting, rich textures, and the dramatic atmosphere of a classic adventure film.
