Subject: Humanoid bionic robot with feminine appearance, matte white shell, black mechanical structural details exposed at the neck, arms and torso, in a side profile, raising its right hand, extending its index finger to touch a hovering holographic touch interface in front with precise and natural movement. Scene: Deep future virtual tech space, no extra physical elements in the background, with several flowing blue arc light bands, multiple semi-transparent square holographic screens hovering scattered in front of the robot, the screens have interactive controls such as radar ring patterns, statistical charts and ring logos. Style: 3D ultra-realistic sci-fi rendering style, delicate and realistic texture, strong future tech and cyber sense, high image detail. Color tone: Overall cool color tone, based on deep dark blue, paired with a large number of ice blue luminous elements, the robot main body uses white and black color matching, the overall color is unified and transparent, with strong tech sense. Lighting and shadow: Overall dark environment with low light effect, only the holographic interface emits cool blue self-illumination, light forms natural light and shadow transition and highlights on the robot's smooth shell, there is a bright dotted halo at the position where the fingertip touches the interface, with slight lens flare effect, distinct light and shadow layers, sufficient atmosphere. Composition: Medium shot side composition, the robot is located in the right area of the frame, the visual flow extends along the robot's line of sight and finger pointing to the hovering screens on the left, the screens are scattered in the left area of the frame, sufficient blank space is left on the left side of the frame, the visual focus concentrates on the position where the finger contacts the screen, the composition is balanced and guiding. Purpose: Suitable for commercial visual materials related to artificial intelligence technology promotion, intelligent interaction concept display, and tech industry, with prominent future and tech attributes.
