For the environment we actually created the full environment for the scene, as a learning process. In the interior of this huge building, we trying to create a sci-fi otherworld combined with spiritual advancement. Here is the shaded version of the environment (Fig.03).
Here is the wireframe version of the environment (Fig.04).
As for this part, it was surprisingly simple. We created the textures for the character and the interior mostly by painting in Photoshop, combined with a lot of metal shaders. The texture is basically a color-based texture to determine the basic color of the character/ interior building. Fig.05 shows a screenshot of a flat render of the texturing for the character.
