Graded Unity Character Modelling

I began modelling my character a few days ago, I'm trying to do it all inside of Max rather than fleshing something out, taking it to Mudbux for sculpting then back into Max for retopology becuase I thought it would be quicker, however I have no experience of box modelling faces, so it's turning out to be quite a challenge.  Also, my design has slightly changed; I had initially planned on making my characters' foremarms and calves very rounded (like Popeye) to be more cartoony, however I couldn't get them looking the way that I wanted so his design is much more normal now.
