Bone to Spaceship Split Transition

A photorealistic split-screen composition transitioning down the center. On the left side, [a small, textured bone resembling a dog bone] rests against [a bright blue sky with soft white clouds]. At the exact vertical midline, the bone seamlessly morphs into [a sleek, futuristic spacecraft] on the right side, precisely continuing the organic contours and silhouette of the bone into mechanical hull plating, thrusters, and panels. The right side is set against [deep black outer space scattered with glowing stars]. Clean cinematic lighting, smooth visual continuity across the divider.
