nice progress Hugo,
If I could, maybe I would add little bit thickness to lips, refine extremitys of mouth,
less distance beetwen noze and mouth, refine eyes shapes
One thing I’ d try to change is forehead. especialy in side view. I don’ t find side view reference
but maybe it is less round, especially near eyes & eyes brows.
About eye brows maybe I would remove those you made (fibermesh ?), eyelashes too,
because maybe it does not help a lot, I don’ t know.
About ears, I would try to focus especialy on them . Meaning watching how others sculpt ears,
or model them, all that can help to define how is build ears, and how you can made them. I assume
it is not the simpliest part but maybe it can add something to your creation.
Anyway,
good evolution, smoother, nicer, you are in the right path I think !
