Lotsa Kudos in the comments so far and it's pretty well-deserved !
.....let me assume you wanted some constructive criticism as well, so here's some:
~ Nice round tone....very good ! I can hear you are really blowing thru the horn most of the time.
~ Your phrasing for a beginner is good too...often it can be disjointed, staccato, letting the notes sorta 'fizzle' out. You are doing well, there.
~ Your upper register. You are changing something in your mouth/throat. The upper reg notes are choking. This is a VERY common dynamic. You aren't confident up there, I can tell. Folks often tighten up their mouth/lips/throat/jaw etc. when they go up high. Work with your teacher on getting the higher register to speak w/o choking....try to keep it as warm and flowing and open as how you blow the low register.
~ Time. You sorta go in and out of time...adding a beat or two in order to get the phrase out. This is being picky...all in all, for 6 weeks, it's pretty good but a few times you lost the tempo and it went awry. This will also improve with practice....just would like you to listen to the vid again and again (counting tempo with your foot) and find, yourself, where this occurred. It's good practice.
Nicely done...and very forthcoming of you to post a vid so early. Keep it up....
