This is MG 1/100 Gundam Barbatos Lupus.
I created a diorama that depicts the title poem (which seems like a death poem...).
The paint job is pearl white over a plated silver base, and then various clear paints in red, blue, and yellow, with the Gundam frame and other parts painted gunmetal.
I wondered if it would have been better to refrain from using plated colors, but since it has a titanium finish look, I thought it would work.
The cape is made of tissue paper painted blue and marked with the Tekkadan mark.
