A little bit of a convoluted process but it works

-Base mesh/block out in Blender
-Pushing details in Zbrush
-Retopo in Blender, BTW Retopoflow finally won me over
-Baking normals in Marmoset
-Head texturing in Substance, Mount done in Quixel Mixer. If I want a realistic material right off the bat I use Mixer for all the rest Painter
-Some light testing in Blender, to see if normals etc. were baked correctly. Plus added the shape keys/rig for the bad meme...
-final renders in Marmoset
