Looking back at my old A'den posts I literally want to head desk so I feel you! It wasn't until Audi reached Master level that my writing with him in particular really matured. I had a lot of fun with that character and hoping Dzia will be just as much fun!
One of the things that helped me was I remembered that I was writing in the Star Wars universe. I took cues from classic/nice films and put them in Star Wars terms, sort of like what Lucas did when he wrote the original films.
