Alex,
Wow! I haven’t checked in for a few days and then I do and I see this WIP! Your a very talented individual! I do have a question, since your working in a water based clay how do you go about drying without cracking and shrinking,etc.? I know that most studios work with oil based plasticine which they later cast in urethane, but that’s a lot of steps. I found a product called Magic Sculpt. It works very well and doesn’t set up too fast. Unlike Sculpy you can easily add to the sculpture after it sets up. However, its does cost a lot more than any water clay especially for a large sculpture like this one.
Thanks so much for sharing your technique with us! And, do take some photos of some of those sculptures on the shelf behind you .
