I used two figures for this scene:
- The Robocop battle damaged NECA
- The head of David (Prometheus) NECA

I first cleared the bottom of the head and hollowed Robocop helmet and the visor holes. I sculpted the head of Alex Murphy from the face of Michael Fassbender (brow and cheekbones arcades), I smoothed the skull glued small parts (washers, square wooden and wire).
I mounted the new head on the neck of Robocop. It can rotate perfectly!
I also repositioned legs to achieve a sitting position.
I carved the screwdriver from the initial gun.
The setting: the poles are made from a broom handle, the boxes are cardboard and base is a cardboard disc on which I glued sandpaper. The "mirror" is a metal strip cut from a can.
I'm pretty happy with the result, although again, the paint provides additional granularity, particulary on the face.
