The background of the box cover seems to be a combat scene in space, even though we haven't seen Exia in space yet.
The action poses are possible since the HG 1/144 scale.
Something new for this big-scale Exia: pilot cockpit with Setsuna.
A new method to assemble the hands, but the shoulder armors are molded together with the arm, and the type of elbow joint used for this Exia doesn't seem to be as flexible as the 1/100 scale version.
The shoe is molded in one piece! Oh dear, why can't Bandai separate it into heel and forefoot as with the 1/100 scale version.
Some stickers are still needed, for example for the front skirt armors.
The shield portion of the GN Sword needs some serious painting (should be in gray, same as the 1/100 1/100 scale version). No improvement ^^;
Part-swapping for the mount racks of the GN Blades.
