I preferred to model the cilias, eyebrows and sideburns to be able to control them better. With a lot of patience you can do this by modeling very thin cones, copying them and slightly modifying them. This adds a lot of realism to your model (Fig.14).
As for the hair on the ears, the clothes and the beard, I used Shave and Haircut and exported about 10 single passes in Nuke (Fig.15).
I exported the following passes from V-Ray: light passes of each light in the scene, diffuse, rawGI, SSS, specular, rawReflection, reflectionFilter, rawShadow, rawRefraction, refractionFilter, 2 multimatte with a few objects I wanted to change a bit, ambient occlusion, 10 hair passes, and ZDepth.
Once I'd composited it all (Fig.16) I used Photoshop to add the cigar smoke and I changed the color curves a bit.
This is the final image (Fig.17).
