I think that I greatly improved at the beginning, but then not so much after for these particular two excerpts. Overall, however, I think that my tone and intonation have improved. I've been trying to improve my tone (and my intonation, which sort of went bad along with my tone) ever since about half a year ago when my quality suddenly dropped and I started getting a ton of airiness--and not much sound. I personally feel that my critical listening has improved, and I am noticing a few more things I wouldn't normally have by listening to my recordings.
On a side note, I finally figured out how to use iMovie (sort of) :D
