The lower torso is literally two hexagonal boxes sitting on top of each other. Yes, that's a full 360-degree rotating ab joint. Good luck with that if you're painting.
The front and side skirt flaps are on sturdy swing arms, but those are on polystyrene-to-polystyrene hinges so don't go crazy with them.
The hip conenctors are actually at an angle and on a rotating core, so they legs will naturally be spread.
Seams to weld/fill: bottom of main hip clamshell.
