掌心托起的線框全息半臉

In a dark space, an open human hand is raised palm-up and offers a glowing holographic half of a human head, built from white wireframe lines. At the middle of the palm a warm orange light gives rise to the face, which dissolves into darkness as it climbs. From the right side of the head, abstract data nodes joined by thin connecting lines stream away, like a digital network diagram. Tiny orange light particles drift through the scene and hint at active computation. Lighting: soft and dramatic, picking out the hand, while the background remains a deep charcoal. Composition: place the subject a little left of center and keep the right side open as empty room for copy.
