Nét Vẽ Nghuệch Ngoạc Buổi Hòa Nhạc với Ca Sĩ Giấu Mặt

A deliberately crude, childlike digital doodle on a plain white background, drawn with thick black marker outlines and rough scribbled fills. The scene shows a humorous live concert with two people: on the left, a seated pianist with short brown hair, pale skin, and a black sleeveless outfit sits on a simple black chair playing a glossy black grand piano. On the center-right, a female singer stands beside the piano wearing a striped black-and-white top and a long dark gray skirt, one arm raised high in a triumphant waving pose. Her face is humorously censored with a square pixelated blur block. The large grand piano is heavily scribbled in black, featuring a yellow Yamaha tuning-fork logo and the word "YAMAHA" on the side, with two small yellow caster wheels below. Near the upper right, handwritten Japanese text "[ヨッメ]" is written in large rough characters, with a black arrow pointing directly at the singer. Intentionally messy amateur style, shaky lines, uneven proportions, with a minimal palette of black, white, gray, brown, pale skin tones, and yellow accents.
