The right palm had to be rebuilt, for it is in fact the left palm (AMT were lazy, and just duplicated it).
The Alien's head was sawed and reassembled to resemble the description of a high-elongated head.
The body-blades (too little of them in comparison to the descriptions, I know) were cut off a styrene sheet.
Blade count: chest-sword; forehead; 3 back blades (arranged in a Klingon emblem style); inner hands' back elbows; outer hands back elbow & top wrist; ankles' dual-blade; and of course, hands and feet claws…
Raul, Aenea and Bettik are originally 3 action figures, sawed and repositioned.
The Shrike, depicted as covered with a mirror-like reflective stasis field, was spray painted with nickel finish spray can (cost a small fortune, but is worth it).
The eyes were painted bright red and outlined black.
The other three were hand painted with enamel paints. According to the books, Androids are blue to distinguish them from humans.
I've made one false detail knowingly - Bettik loses his arm after this scene, but I've decided it'll look cooler with his hand off.
The river was done with a 40/28/5 cm polystyrene block, covered with crushed paper and painted with acrylics.
The raft was made of pieces of polystyrene, plastered and painted different colors to look like tree trunks, all tied together with rough wrapping string.
