Ok, subscribed your trello now 
Wow geometry optimization is on the way now:D, but does it help corona displacement to consumes lower memory?
Any advice to make the skin looks softer?? SHould I use both translucency and refraction?
maybe try to reduce bump value, for me it’s looks like have tone cosmetic powder.
And no you should’t use refraction for skin because it’s not have IOR.
Do not like glossy horns(
you are right, maybe if I blur the displacenet it could be better?
The horns material has 40% glossiness, is it too high?
IMO, you should “break” the glossiness between horn and face.
It’s stange that the skin has the same specular level of horns.
This.
I’m by no means a 3D character expert (I can’t even fathom modelling what you’ve done!) but from checking out a few ‘making of’ videos the most realistic ones use hand painted reflection and gloss maps (as well as skin pore maps). For example the bridge of the nose and forehead is usually fairly shiny on most people, but the side of the cheeks and eye sockets are quite matte.
thank you all for the advices! I really appreciate
Of course it has, everything has index of refraction. I remember i read somewhere that actually skin has quite high IOR - over 2.0, but i couldn’t swear on this exactly. And yes, to use refraction for skin in Corona is perfectly valid method. I tend to use translucency, but mainly because i hate how objects displayed in max viewport once refraction goes below 1.0.
Another test, this time I added some estra cavity texture on the horns, drastically decreased the reflection and the glossines and increased the displacement. I also decreased the displacement on the skin and added some grainy bump
too much diffuse I guess..
