I modelled this in Blender after following an awesome tutorial from BornCG. Anyone struggling to get to grips with Blender I strongly recommend his tutorials. I hadn't touched Blender in 2 years as I couldn't get on with it. I found BornCG's tutorials and 2 weeks later I love Blender.
Had to cheat on the textures as I couldn't get textures with transparency to work properly in Sketchfab so these have a yellow background same colour as the head.
The blender file has all the parts parented and constrained correctly to allow easy animation.
