After the mesh is retopo'd in 3D Coat software, the polygon face is reduced from over 2m to less than 50k. I also use 3D Coat to paint the texture.

So far the Monster has oceanic look with coral-style texture, and the costume design is given a bit military character. As for the Samurai, I tried to keep it as simple as possible, but still painted with a few details such as tattoo on the chest, scar on the face, 'cause he is supposed to be a senior veteran samurai who had survived many battles...
