The front and side skirt armors are poseable to avoid interference with the leg articulation.
The hip joint axis can swivel forwards and backwards on one side.
The upper thighs can swing frontwards (and backwards in a limited extent due to the non-poseable rear skirt armor) on a peg joint, raise horizontally, and/or rotate on each piece.

Tips & Tricks
For better results, some/most of the details are needed to be applied/panel-lined with Gundam Markers/Mr. Color Paints.
Topcoat (Mr. Hobby recommended) can be used to protect applied stickers and if any, marking decals and painted details.
If using matte/flat-finish top coat, it is advisable not to spray on the translucent parts - can be done by masking or spraying top coat while the said parts are separated.
Take note that the Gundam Shield adapter's clamp is held by friction, so it can potentially fall off on the straight-built left forearm unless the forearms are painted and/or topcoated in a few thin layers.
Care must be taken while assembling the ball-jointed waist armors: depending on the thickness of your painted waist sockets, the ball joint can eventually create stress marks (or even worst; potential breakage) on the sockets. It's recommended to wipe off the excess paint on the sockets with a cotton swab doused with either thinner or the Gundam Marker Eraser pen's liquid.
