Thanks, all...I really appreciate the positive feedback.
I do intend to sculpt Mateo- I have been waiting for him to grow into his adult, "big boy" head. Well, he's almost 3, so what I see now is probably what it is. And it is big; I'll probably scale it down in size, 'cause that's a lot of clay, lol. He will be fun to sculpt...
CeeCee- I do use caliper measurement for humans- not so much for dogs. I usually don't have as much personal contact with them; or if I do, calipers would scare them, or make them nervous. I usually use photographs- whatever I can get. Better if I can take the photos myself, but that's not the norm.
Mary- I would love to sculpt one of your corsos!
*Note: If anyone is interested in a custom sculpture of their beautiful dog (or human family member)...just pm me.
