looking great so far. as for Zsketch and hands/fingers I would think using Zspheres for the armature is still the way to go, especially with the updates they have made. (looks like the mesh is created a bit cleaner) then use Zsketch to block in the rest. I'm definitely also going to check out Ryan's new Zsphere/Zsketch tut's as there is guaranteed to be some great techniques for using them.
I've used a zplugin called zshpere tweaks before and it works pretty good. The plugin allows you to adjust the zsphere division levels after you have created everything. I don't think it works in 3.5 though
