Pretty sure that the 'statue' is a second set of the armor put on a cheap mannequin. If you look at the ankle you can see where the mannequins ankle couldn't bend properly for the pose, so they disconnected the ankle.
This would explain why the suit and the statue don't match exactly... I suspect that the statue wasn't assembled properly.
appears to be at either the COEX mall or the IPARK mal in seoul. i could be wrong tho. appears im not the only one in korea who has MC armor. This shall be fun when mines finished. does anyone know who that guy is who has the armor? id love to hookup with them to make a video with our armors.
EDIT: My katusa buddy said its the IPARK mall in seoul. also on the second video when the backplate falls off it says something to the effect of "oh **** my 8000 armor " having a good buddy who is korean to translate comes in handy lol
