Snakey Guy 3D model

Snake guy I made in Zbrush, rigged in Blender using autorigpro, included is the base file with textures packed in Blender 3.6 and then another file with a simple tongue animation(see video) The mouth animations are done with shapekeys - the tongue has a seperate bone armature from the rig - the topology is bad(you can see in the gallery)
