I am absolutely a fan of metal armor. But you have to have a body strong enough to hold it. If you do go plastic, it has to be rigid. Armor that bends and distorts with posing immediately makes a piece feel cheap.
FYI the body inside is Toys Era ‘the Steel’ Colossus. The boots extend the height by a few inches beyond that. This thing is way too big for a believable 1:6 Spawn.
