Rhetoric Camel: thanks ffor your comments and sorry for bringing back bad highschool memories
Zbrush does make organic modeling a lot easier, and more enjoyable. Although it still requires exactly the same patience and attention to the basic principles as any other software method. However making changes to form are far more intuitive and speedy, and it will allow you to take you work further. Until the next version of maya when perhaps it will get the mudbox intergration which would be interesting.

I'll be flitting between this and the soldier character at the mo as I needed a break from creating old men in suits, as this one is the third 'suit' I needed for the opening pages, but then things get more interesting.
