原始提示词
Create a detailed pencil sketch illustration with selective blue color accent of {argument name="character name" default="a handsome young man"} joyfully riding a vintage bicycle. Show him from the waist up in a front-facing three-quarter view, hands firmly gripping the curved chrome handlebars, smiling broadly with visible teeth and bright expressive eyes, looking slightly off to the viewer’s left. He has tousled short dark hair blowing naturally in the wind and a neatly trimmed beard. Dress him in a long-sleeve button-down {argument name="shirt color and fabric" default="bright blue denim"} shirt with rolled cuffs, visible stitching, two chest flap pockets, open collar, and realistic fabric folds; keep the rest of the drawing mostly monochrome graphite except for the blue shirt. Include exactly one vintage bicycle with a curved handlebar, brake levers, front headlamp, central stem, partial front fender, and visible hand grips, rendered with precise mechanical linework. Place a soft, finely sketched {argument name="city skyline" default="New York City skyline with One World Trade Center"} in the background across the horizon, with multiple thin high-rise buildings and a calm waterfront behind him. Use a clean white paper background, realistic hand-drawn graphite shading, crosshatching, delicate contour lines, high facial detail, crisp hair strands, natural proportions, and an airy editorial fashion-sketch feel. No text, no watermark, no border, no photorealistic color background; emphasize the joyful motion, windblown hair, and the contrast between the vivid denim blue and grayscale pencil drawing.
