Jeh, I can hear a tremendous difference in your voice! You have gone from a high soprano* to having a darker, weightier voice. The musicians that you work with MUST have noticed, what are they saying?
I listened to your above three posted links in reverse order. In the one where you say 'This is my voice after 4 weeks of T', you sound as if you have a slight cold. I listened to the second link 'This is my voice after 1 day of T' and you can really, absolutely hear the difference.
In my opinion right now you have darker, grainier voice, you sound like a dramatic mezzo who has a lightness and a softness in the upper register.
