thank you, yes I used zBrush for quite all the project (except part of post processing: Photoshop, and part of the retopo:c4d)
And yep even if a project is not finished, I usually like to continuously check it with bpr render (at specific moments, some changes, adding elements, etc)
first because rendering is a complete and essential part of the creation (in my humble opinion). so I (we?) have to practice it as much as we can.
same thing for post processing ( wich is quite too often considered as a sub 'art' or is denigred by few artists because they think it is cheating, etc...
yes you can 'cheat' if you are decided to, but if your aim is to learn how to enhance render, with its passes etc, then it is a crucial part that has not to be under estimate in my opinion but every one do as he wants of course ^^)
And why maybe it looks not 'wip' is maybe because I often start with the face,
givin it maybe more attention, wich explains why it is advanced state (relative to its body, etc)
And to finish to explain why I usually make my wip like a final render,
is to practice and maintain the 'final creativity', even if I think that it is alway better to start with a story (even if we change it during the project) (I especially lack in this matter).
Anyway, thank you again Melissa,
I hope I have not bored you (and not afraid you with some of my english 'skills
