If I close my eyes and listen to the first two samples, yes, while technically *low*ish, you definitely have a feminine register. No question. When eyes opened, and taking in the whole package, you should be quite pleased.
Listening to the last sample sent to Dr. Haben, it sounds like you are on your way to having a sexy, sultry voice as others have commented. Obviously each case is unique, & their are ups/downs. However, you are well poised to have a very good result.
I haven't heard your original untrained voice, and that would be interested, especially for those considering the surgery, such as my self.
