Which details does the author describe about Ostropov from Lost Translation by Eva Hoffman?

Hoffman notes that her new music teacher, Piotr Ostropov, is a Russian gentleman, and that he resembles an artist, a romantic, or at least the nineteenth century ideal of one. Ostropov has a large bald spot with white bristly hair sticking straight up. His eyes are bright and contain an impish glint.

Hoffman describes Ostropov as a musician, who is both "a wizard and a snake charmer about to make water spring from a tree branch and transfix his listeners with his power." She adds, "His eyes twinkle, and he looks up at me like a magician who has just accomplished the naughtiest, most amusing trick."
