MG Wing Gundam Zero ver. Cupid
According to the modeler…
Some of his favorite Gundams start to be yellowish so instead of letting it go, he recreate concepts with new design and theme. This Wing Gundam was yellowing around its wings as well as around the arms.
As for the colors, he used the following:
Blue -> Metallic Purple + Glossy Blue (Base)
White -> Metallic Gold + Sparkling Gold (Base)
Inner Frame -> Metallic Grey (Sort like gunmetal)
