Lovely cohesive backstory and I appreciate the amount of detail you added to her personality and relevant abilities! I advise you to take a second glance at the characters of the ship as Savva, much like Mamjir, will have been already recruited and have some type of relation to each of the crewmen. I see nothing wrong with this sheet, but out of curiosity, would you say Savva has some kind of long-term goal? From past experiences (mainly DnD), characters with an already-established goal are often easier to drive their story forward with. Extra points if it is a clear goal like Arzhang Deko's goal of becoming a lavish waiter, or Mamjir's goal of serving the duty set upon him.
