Hellbeard,
Been a while since I've looked in on this thread. Great stuff. Even more improvement than the first time I visited. Your faces are getting much more expressive and I think you are doing really great with the hair. I haven't been able to grasp how to add a mustache to a mini and you give them a nice full head of hair.
The only problem I see, and it may be a trick of the photos, but some of the putty could be smoothed a bit more. I'm just afraid once they were cast you wouldn't be as happy with the result. Nice smooth putty will give you a nice smooth cast.
Keep it up.
