Well here's Octavia as bounty hunter in The Mandalorian universe. Her outfit and armor is not based on any specific character from the series, but instead it's a collection design elements I found in my research.
Same is true is for her weaponry. The Mandalorian blaster pistol is heavily influenced by the Bergmann -Schmeisser 1894 No1 pistol. Ian at Forgotten Weapons has done video about both the pistol [Link](https://youtu.be/SGNPqqau-E0) and its appearance in the TV series. [Link](https://youtu.be/JvGa2c3rEuE)
In fact it was the use of actual firearms as design inspirations in the Star Wars universe that really fired my imagination, a long with the awesome space ships designs, and set on the path of being a professional illustrator.
So for Octy's pistol I drew inspiration from another late 19th century, Austrian semi-automatic pistol the 1891 Schonberger-Laumann. [Link](https://youtu.be/AFhU3Dixvnk)
