shinkai makoto style, hyper-realistic anime, a boy cycling downhill at extreme speed on a winding summer mountain road, sea and sky in the distance, ultra-realistic motion blur on ground and surroundings, wind particles and flower petals flying, shirt and hair blown violently by wind, camera fixed directly behind the woman at very low angle POV, never rotating or panning, tracking closely just above the rear wheel, no face shown, body moving dynamically with balance, shadows racing on the path,
