Me after 3 months practicing Saxophone.

In June this Year I decided to learn my first music instrument. Aging 46 Years I start to play Saxophone. After a few less than 3 Months practicing about an hour each day, it sounds like this.
I still can't read notes, so I practice a lot of long tone exercises and scales and learn some simple melodies just by ear (try and error). Melodies like those I play in the Video, or "Amazing Graze", "Lean on me", the "Lonely Shepherd" and so on. I have about 10 melodies I'm working on and repeat them over and over and over again. I also do some first free jazz improvisations (simple and limited to a few notes, it sounds not that bad, says my wife) and some simple songs by notes, but imo understanding all those different lumps sitting on their lines and having all those flags on and points and other signs in between, that's the hardest part of all.
Btw: my Instrument is a Yamaha YAS 280 student's Sax. I play it with original Mouthpiece (4C) and original Ligature, mostly use Vandoren Classic Blue reeds in 1,5 strength.
Mostly. Yet. My embouchure isn't developed enough to practice a whole hour with stiffer reeds. Often I start long tones and scales for about 15 Minutes with strength 2, then switch to 1,5 to play melodies and also scales & long tones. When my embouchure is still okay after about 60-75 minutes of practicing, I switch back to 2,0 or even 2,5 and do some minutes long tones again, to end my daily practice session.
I have so much joy practicing this Instrument, I often can't take my hands off it.
(eg. do another 10 or 20 minutes of "dry" finger exercises after cleaning it)
Maybe I'll never be a great saxophone player (surely I'd had to start earlier in my life and my talent isn't also remarkable) but I have my fun anyway...
Let's do this journey step by step and see in 2 or 5 or even 10 Years, where it has brought me.
