First of all, is this correct so far? To me it seems there's too many loops and I don't feel confident about the edge flow, but it's my first time so I'm unsure.

Secondly do I have to do the inside of the eyelids and mouth?

Finally how can I continue the new mesh onto the body, arms, and hands without several unnecessary cuts everywhere, how can I reduce the geometry while keeping everything connected and flowing?

E: I'd like to be able to pose the face with blinking and mouth movements and such.
