At long last, we finally have a picture (outside of the one illustration which is briefly showing her in book 1 of Taylor's series) of our dear snow leopard, Natalia Ruyemov. Guess it is best to describe her by the description given to her in the character glossary in the back of book 1:
"Coming from the far western country of Livarnu, she was prior military for her country and served alongside Mikhail, whom she considers like family. She is devoted to her friends and usually ends up going where they go when they swap jobs/missions. She had a little sister, Sarah, who was sent to Zabökar on an exchange student program."
