This is Petya's sister, Inessa. If you are wondering where the names come from here's your answer: Child 44 by Tom Rob Smith. It's a book I read this summer and to keep track of the characters I write names down. Sometimes I write down minor characters' names just because they sound neat. Then I have a list of names to use for my people I make.
Both Petra and Inessa are about 20 inches tall. The picture below shows her back.
Again, Susan claimed these pieces and attacked them with her stencils and spray paint.
