Personality of a German Sheperd mixed with Pitbull?

I know that all animals are different. I would just like to hear from people who have or know of German Shepherd and pit bull mixes- what was that particular dog like? were they naturally protective? etc etc? I have a German Shepherd pit bull mix named Diamond. She is 4 months old now. I was just curious of how others dogs are that are this same mix. Thanks!
