机械键盘

Designed by Shuhuang Xie（ID:折纸盘菜） Fold by me(PAN.Hang) This an evolution version of Agumon in the famous anime "Digimon", see more info. about" Metal Greymon It was my first attempt which I tried to test the CP, the design was based on 64X64 grids. box-pleating( octopus base). I should say very cool model, the wing part is my favorite, but I folded the hand part opposite, and I should shape the legs better, I will fold one more, maybe try color-change:) One square of yellow paper-mulberry paper, CMC used in the final shaping.
