文化IP GPT Image 2 提示词：MS Paint 风格查理·布朗旗帜涂鸦

Create a deliberately crude Microsoft Paint style cartoon illustration on a plain white background, with thick uneven black outlines, wobbly hand-drawn shapes, scribbly brush fills, and a childlike digital doodle look. The single subject is {argument name="character name" default="Charlie Brown"}, shown from the waist up, smiling calmly at the viewer with a round peach-colored bald head, one small curl of hair on the forehead, dot eyes, simple curved nose, round ears, and a wide curved grin. He wears a bright {argument name="shirt color" default="yellow"} short-sleeve collared shirt filled with messy scribble strokes. His left hand grips a tall brown wooden flagpole angled slightly upward along the left side of the image. Behind his head is a waving {argument name="flag type" default="American flag"} with a blue canton full of many irregular white dots for stars and red-and-white horizontal stripes drawn as rough uneven bands; the flag is outlined in black and appears attached to the pole. Use a square composition, centered character, playful nostalgic Peanuts-like proportions, intentionally imperfect MS Paint brush texture, no text, no shadows, no realistic rendering.
