I decided to sculpt Sari. And I'm very happy with the result. The 9-cm (3,5") tall figure is perfectly character-accurate! I never was hoping for such good result! And now I'm afraid to apply paint as I afraid to ruin it...

[link]You can see there preliminary body structure on wire-skeleton and finished figure. Her key is removable and it can be attached to any hand

I was too possessed by the process of sculpting that I forgot to take step-by-step pictures... So you can see only the base and the finished picture. If someone is interested, I can write down the whole process in comments. Just ask
I'm not sure about when I will colour it cause I want to buy some new paint for this figure as my current paint leaves uneven surface and I don't like that.
You know, my camera is crappy so face-details are almost visible at the moment... Sorry again that I torture you with those bad photos. I promise that when I finish with paint and if I will be happy with colours, i will go to photo-studio to make professional pictures.
