Комичный сёнэн-манга разворот

A polished full-color shonen anime manga splash panel based on the reference layout. Four characters in a dramatic comedic scene: centered in the back, a large muscular male student flexing; on the right, a blond male student flexing; on the left, a small white-haired student in a crouched power pose; and cropped large in the lower-left foreground, a red-haired character reacting in shocked disbelief. Clean inked outlines, crisp cel shading, and colored Japanese school uniforms. High-energy background featuring dense blue radial speed lines, comic halftone dot textures, stylized blue and yellow stars, and yellow explosion burst accents. In the lower right corner, a jagged comic speech bubble with vertical Japanese text reading "[なにしてんの?]". Dynamic, vibrant, saturated colors with sharp anime line art.
