A beginner starting on a very soft reed can blow and get a sound without much air or embouchure support. The upside of this is you can easily make a sound and start making progress right away. The downside is you have no control, and intonation suffers. I would go up a notch on the reed strength so you can both blow harder and start to build your embouchure strength. There is such a thing as having an embouchure that's too relaxed. And that's where you are right now out of necessity due to the extremely soft reed. I can tell you're biting to maintain control rather than using your embouchure and this results in going sharp. Plus you need to start using your ears as others have said.
Aside from that, you've got a great tone from top to bottom, good rhythm, nice technique on fingerings and scoops. Keep up the good work.
