Unfortunately all her social media are in Russian, so I can't tell you more about her than you can see for yourself when you browse through her photos.
I am not sure about her technique. She must be starting the sculptures by dry felting them. But there are some pictures online where she soaps the surface and rinces with water. It would explain the smooth surface.
I am curious to see if she uses wire to support the structure. As you can see in one of the photo's, the dolls are quite big.
It is an absolute inspiration for me to look at these pictures and I only feel more compelled to keep working on my own dolls.
