藍天下穿紅襯衫的鬍子牛仔

a modern stylized illustration inspired by Enki Bilal & Moebius of a mature Caucasian man with a thick white beard and a weathered, kind face, looking straight to the viewer, stands outdoors under a bright, clear blue sky with subtle hints of wispy clouds. He wears a classic cream-colored cowboy hat, its brim casting a slight shadow over his eyes, and a light tan, long-sleeved Western-style button-up red shirt. The shirt is slightly unbuttoned at the collar, revealing a glimpse of a darker undershirt, a stone-washed denim jeans, accentuating the muscularity of his forearm. A sturdy, well-worn brown leather belt with a silver buckle cinches his waist. The lighting is bright and natural, suggesting daytime with the sun high overhead, casting sharp shadows and highlighting the textures of his skin, the fabric of his shirt, and the denim. The composition is a medium close-up, angled from slightly below, looking up at the man, emphasizing his presence and the vastness of the sky behind him. The overall mood is one of quiet confidence and rugged simplicity, with a painterly, illustrative graphic novel style that emphasizes form and light.
