Authentic Japanese shonen sports-anime illustration, the exact same character as in the reference sheet (short spiky dark-brown hair, shirtless, black shorts without waistband, bright blue sneakers). Strict side view, FULL BODY SMALL IN FRAME: the character fills only about 45% of the image height, centered, with LARGE empty space (at least 35%) above his head and at least 10% below his feet. He is at the very top of a burpee jump: both feet clearly off the floor, knees slightly bent, both arms stretched straight up above his head, fingers open, joyful powerful expression, light speed lines under him, subtle red glow on the thighs. Same bright clean white modern gym background in anime style as in the second reference image, soft blur, one seamless full square canvas, no inset boxes. No text, no watermark.
