After a few more changes (adding shapes to the face and actually rigging the tongue), I set up the Sune model to be ready for sharing. So now anyone who wants to mess around with the long snek himself can!
Feel free to use the model however you like (edits and ports are allowed)

- Fresnel-based outline (Tied into materials)

- Curve-based posing for the Tail (Tail set to fit the length of the curve)
