A dramatic, painterly illustration in the style of classic Western book covers, evoking the spirit of adventure and the vastness of the American West. The central focus is a majestic, proud Native American warrior, depicted from the chest up, with his face turned slightly to the side, exuding wisdom and stoicism. He wears traditional regalia, featuring intricate beadwork and feathers, rendered with rich textures. Behind him, a sweeping vista of rugged, sun-drenched mountains under a dramatic, expansive sky painted in deep oranges, fiery reds, and dusky purples. A lone eagle soars high in the distance, a symbol of freedom and vision. The overall mood is heroic, slightly melancholic, and awe-inspiring. The composition is balanced and dynamic, leading the viewer's eye through the scene. Professional audiobook cover aesthetic, square 1024x1024 format. NO text, NO letters, NO words, NO title, NO author name — only visual artwork.
