"Animate the character’s head through one smooth, continuous upper arc from the top-left orientation in the first frame to the top-right orientation in the last frame. The head travels naturally through the entire arc. Torso, shoulders, suit, and overall body remain completely stationary. Hands and gun move subtly and synchronously with the head, following the same rotational momentum. Preserve the character’s proportions, low-poly 3D style, and facial features exactly. No body translation, no camera movement, no zoom. Smooth, controlled, continuous motion."

让角色的头部沿一条平滑、连续的上半弧线运动，从第一帧中的左上朝向转到最后一帧中的右上朝向。头部自然地走完整条弧线。躯干、肩膀、西装以及整体身体保持完全静止。手部和枪随头部产生细微而同步的移动，遵循相同的旋转惯性。严格保持角色的比例、低多边形 3D 风格以及面部特征。不做任何身体位移、不移动镜头、不缩放。动作保持平滑、受控且连续。
