I created a diorama inspired by the box art of the old 1/144 Perfect Gundam kit!! 
The Perfect Gundam is the old 1/144 kit, and except for changing the power pipe to a spring pipe, it's assembled in a straight line (although after completing it, one of the horns on its forehead broke, so I had to cut the other side to balance it out...)
The Perfect Zeong is based on the legs of the HGUC Zeong and Sazabi, but with some modifications.
