This is a Kanu Unchou model kit I finished earlier in the year. Its based off one of the season 1 DVD artworks. This is the second version. The first has her with the panties fully pulled up, and he breasts aren't showing. On this one, he shirt is pulled up, revealing her breasts, along with her panties pulled half way down. This was sculpted by Griffon, who usually due nude Ikkitousen model kits, which lack the sculpted anatomy detailing down below the waist line.
I use an airbrush to paint my model kits. For this model, I used pastel to shade in the darker parts, then blended those colors in again by airbrushing the original skin color.
