Not only is there the question of the definition of a 'proper face' there is also the question of what you are trying to achieve.  I do not have the skills to create my own figure but I wanted something different so I used V4 as a base and then mixed a number of characters and then did a bit of dial spinning.

I also changed the eyes as I dislike burnt in reflections and only the very best characters appear to have the no refection option.  The end result was a character I called Cadhla. Does she have a proper face? Most certainly not, but the aim from the start was not to be photo realistic but believable.  The aim is the same in the Sci-Fi scenes she is discovered in, often purchased and with the textures tweaked or post worked to try to achieve the belief that such a setting 'could' exist.

More to the point I have used this character in my renders to illistrate a book I am writing for my own pleasure and members of my family.  As such she has taken on a believeable personality which must mean I see something others often don't.

It is a bit like reading a book, each reader will see their own hero or horoine, who is the say which version is most proper.

 

 

I use Poser 13 on Windows 11 - For Scene set up I use a Geekcom A5 -  Ryzen 9 5900HX, with 64 gig ram and 3 TB  storage, mini PC with final rendering done on normal sized desktop using an AMD Ryzen Threadipper 1950X CPU, Corsair Hydro H100i CPU cooler, 3XS EVGA GTX 1080i SC with 11g Ram, 4 X 16gig Corsair DDR4 Ram and a Corsair RM 100 PSU .   The desktop is in a remote location with rendering done via Queue Manager which gives me a clearer desktop and quieter computer room.
