I know that the Halloween has finished. But Bertie comes to CGTrader just before the End of Year Holidays:

Altough this model sculpt is intended to be 3d printed, it taken a bit more time because I tested on it the new texturing tools in Marmoset Toolbag 4.
Modeled and Sculpted in Mudbox 2019.1
Normals, AO, Curvature and the rest of the maps for the textured version for the beauty renders, were baked on Marmoset Toolbag 4.
Textured on Marmoset Toolbag 4 too.
Renders: Marmoset Toolbag 4.
This 3D sculpt model is intended to be 3d printed.
Sliced, Keyed and inspected in Autodesk Meshmixer.
