Hello Miss Saxophone,
I think it is great that you are keeping a blog of your progress and making videos.
I hope you don't mind but I took the liberty to analyse your audio:
The red sections indicates that you have clipped the signal, and this has created a lot of distortion on your recording. For future recordings it would be worthwhile seeing if you can reduce the mic gain, looking again at the analysis, I would suggest by quite a bit. We will then have a much cleaner recording on which to comment on.
Best wishes,
Chris
