Fully rigged with 61 looped animation clips. Of course, you can create your own.

This model has about 40k faces so it's suitable for game engines such as Unity, Unreal, etc.

You can also enable displace and subdivision modifiers for high-resolution mesh if you want to render a shot for a movie or video.

The model is PBR and includes 6 Color variations textures at 8k. 

Also 5 Roughness Maps, a Normal Map (OpenGL and DirectX), a SSS mask, and a 32bit .exr Displacement Map.

Eyes, chest scales, and neck feathers are different meshes so you can disable whatever you want.

Here is a Google Drive link where you can download and play with a scene I created in Unity. It's only a prototype so there are only basic functions.
