Tbh it’s good flying but your flying to fast that why it’s shaky and you loose control. Even tho it is boring try flying slower and more controlled. Try to make it smoother and the better you get the faster you can go keep up the good work.
Edit: it also seems (and I have this problem too) you get too comfortable and start doing things beyond your skill level. Start with the basics and slowly work up. Patience sucks but it’s worth it in the end.
On the parts you did go slow on the video, I saw way more control and it look very professional. I can tell you are going to get it. You got this.
