Social Media Post - Anonymous Concert Doodle

Create a deliberately crude, childlike digital doodle on a plain white background, as if drawn quickly with thick black marker and rough scribbled fills. Show a small concert scene with exactly 2 people: on the left, a seated pianist with short brown hair, pale skin, black sleeveless outfit, sitting on a simple black chair and playing a glossy black grand piano; in the center-right, a female singer standing beside the piano, wearing a striped black-and-white top and a long dark gray skirt, one arm raised high in a waving or triumphant pose. The singer’s face is anonymized with a square pixelated blur block. The grand piano is large and extends to the right, heavily scribbled in black, with the yellow Yamaha tuning-fork logo and the word “YAMAHA” visible on the side; include exactly 2 small yellow caster wheels under the piano. Add one handwritten Japanese annotation, {argument name="annotation text" default="ヨッメ"}, in large black characters near the upper right, with a black arrow pointing toward the singer. Use an intentionally messy amateur style with uneven proportions, shaky outlines, visible scribble strokes, minimal color palette of black, white, brown, gray, pale skin tones, red cheek accent, and yellow logo details, like a privacy-protecting humorous sketch of a live music concert.
