Final Design and Model Sheets

I have narrowed down the final design of the character.  I think it successfully captures the likeness of my friend and manages to look quite stylish at the same time.  I will begin modelling as soon as possible and aim to have the rig working as quickly as possible.  I attempted to do an expression sheet to use as reference when creating the final poses for render.  Most of these are successful, but it will depend on the complexity and the ease with which I can use the rig to create these expressions.
