This 3d model is supposed to be a futuristic snake creature.
Texture maps are 4k for first part, 2k the rest and 1k for the eyes. It's got diffuse and bump maps. The UVs for the body is extended on 4 squares, each one for different part of the body, for a high resolution image, done with .png and .tif formats.
It's fully rigged and first segment can be animated separately from the rest of the body, without disturbing the tail, like a classic spline rig. You can make the tail shorter. Different poses or motion tracks for the tail can be achieved with blendshapes for the spline curve.
The scene has the pose seen in the previews, for example.
