I tried to recreate the scene from the first episode of Gundam where a beam sabre pierces the cockpit of a Zaku, using the HG G30 Gundam and 08th MS Team HG Zaku.
Are you still working on recreating this scene?...
I took a photo from the same angle as the anime image, but the beam sabre wasn't very visible, so I changed it to a slightly higher-angle view.
The Gundam was painted with lacquer for shading, then painted and dry-brushed with enamel.
The wrists were loose, so I replaced the poly-caps with disc-shaped ones.
