This made me remember the fact that I (kinda) did the same project, only difference being I had the Shining Gundam from the same line, and instead of jamming a G-Frame in it, I just made a shittier version of it with cutting some small areas around the legs to give a wider leg spread and knee bend (the knee bend was slightly disappointing as it didn't give a whole fuck lot, but it did better than it did before), as well as installing some small Lego parts inside the body to give it a slightly loose but workable waist C-clip joint, and gave it my HG revive RX78-2's hands (I didn't really have much use for them as I am planning to buy a new one to convert my original one to the Last Shot Ver.) and dubbed it "the Ultimate No Grade Shining Gundam" which was already an overstatement, as it has the niche 2000s HG range of articulation, only to become a bigger overstatement compared to yours, besides that little story, this was a pretty great build of the God Gundam, and I love how you painted it honestly. The title of "Ultimate No Grade" belongs to that very build, king
