I started giving Zbrush a try last night - it was frustrating at the start (like with all new programs, heh), but this morning I got a little more used to it and now I'm quite enjoying it!

I don't think it looks like me >_>. Lots more need to be done, like the cheekbones and forehead, and the features probably need more tweaking too.
