Here is old-new work from me...
Yes, it's still my Grandpa, but this time finally with textures.
I've changed a bit the model. All textures are made by hand, the fine detail also made by hand. No photo textures used.
Softwares used:
3ds Max: modeling, retopology
Zbrush: sculpt
Mari: textures
Substance Designer: tileable base color texture
Maya Vray: shader/render
Xgen: hairs
Nuke: "compo"
