钢笔速写画风格 - FLUX-V1

GBSX, Digital pen sketch of an elderly man with a long, gray beard and wrinkled face. He's wearing a loose - fitting, checkered shirt. The style is minimalistic, with thin, wavy lines that capture the essence of his features. His eyes are half - closed in a contemplative gaze, looking straight at the viewer. The plain white background highlights his weathered appearance, giving the drawing a relaxed, spontaneous vibe.
