Yep I agree that your voice is pretty good Stephanie_b, especially if you've just started!
I think I know what you mean by "raspy" voice when I hear yours. For me, as I slowly used my girl voice more and more, it slowly went away without me doing anything about it consciously... so keep using it!
Here, I recorded my voice too
http://picosong.com/wRyB I have quite a low speaking voice as you can hear - this recording, for example, averages only around 190 Hz! So I overwhelmingly rely on resonance rather than pitch to sound like a girl. (By the way, what I said in the audio file about Samantharz in the file probably isn't quite true, but anyway...)
Oh I'd like to add that I didn't try to consciously learn any feminine ways of speaking (or non-verbal actions), but I just seemed to naturally talk and act more feminine as I thought of myself more as a girl...
