Most of the foil stickers included are for the head actually.
Like Exia, the name of the Gundam is molded on the forehead - much like the unit code on MG Hi-Nu, Strike Freedom and others.
See the parting line on the back of the head? It follows the part separation of the head ^^
The design of the arm unit is exactly the same as Exia, and the Twin GN Drive is mounted on the shoulder instead of the backpack.
Someone should really ask Bandai why is the ability to combine the weapons not included for the HG version, when it's just another extra part needed for the handles ^^;
The square insertion points on the shield look very suspicious ^^
Display stand not included. It's borrowed from Force Impulse.
Also under construction on the same website is BB Senshi Sangokuden Shuuyu Hyaku Shiki:
Much like the treatment for MG Hyaku Shiki with Ballute System, the color molded is yellow instead of gold.
Got to love the part separation for the forehead ^^
The color of the front of the feet is missing. Stickers included I think.

On the other hand, Taste has completed and reviewed his painted BB Senshi Sangokuden Shuuyu Hyaku Shiki.
Super nice after painting ^^
