Here is my version of Uncle Fester from Adam's Family but based on Larry Fine from the Three Stooges... I grew up watching these two shows and I always thought that Larry would have been a great cast for Uncle Fester.
All done in ZBrush, textures in Substance Painter and rendered with Arnold in Maya. Marmoset Toolbag 3 used for look dev, testing maps and lighting.
If you are interested in the resources used to detail the skin, I put together a ZBrush brushes pack for skin that you can get here: https://www.zbrushguides.com/zbrush-skin-brushes-pack/
