not to hijack it but you know, coffee, my currently fav thread and so on 
Eyelashes:
-very few fibermeshes (lower lid less than upper),
-thin tip as they aint cut like beard usually
-upper lashes negative gravity > -1 , lower lashes positive gravity < 1
-mask outside the lid for lower, mask slightly below and inside the upper lid (check your own eyes lol)
-there is no hairs at the very left and right edges of the lids
-it helps to use gravity and the on screen bottom orientation of your model to have fibers fall in the direction you want before even styling, good for beards, eyelashes, etc
Eyes:
for the eyes he showed a few short how tos a few pages back, theres a tutorial somewhere that explains it a bit more (just google aint hard to find),
-basicly a high shiny white sphere, slightly elongated at the iris area,
-then a flat disc woth a hole as iris without any spec and another sphere encasing iris and eyeball
-that outer ball gets a black, no diffuse, high spec material and you set its display properties to render transparent in BPR
to make it look as realistic as Hossein did… well… practice i assume
the proportion eyeball to iris is important (golden cut not-quite-half actually if im not off) as is the size of the eye opening in the middle of the iris in relation to the expression, also the polypaint and sculpt of the iris gives some realism or not depending on skill
skin shader looks perfect.
