Here is a WIP of the modeling and redesign of a character I created some years ago for a CDC.
I'll go for a PBR render and I'll (try to) do the hair in alpha for a change and for a good exercise.
Here in Unity with Normal only
Unity with Normal and unmodified AO
High poly in ZBrush
Low poly + hair cards. First time trying that way of rendering hair, still working on it. Next step: PBR in Unreal !
