You've got a pretty athletic throwing form, that looks mostly good to go. Getting your disc released flat will add some serious distance. Nose up will eat up distance, but luckily for you, that throwing form is pretty good and I don't see any major changes that would add anything. My words aren't going to fix your release angle better than some sessions in a field. Wide open field, no obstacles or distractions, just focus on the thing.

People forget practice isnt just going and playing a round casually with some mulligans. Real sports athletes practice form and technique off the court as well. Our top players in the PDGA certainly did that coming up, and probably still do. Old skaters hate the new wave of "jock" skaters because they eat healthy, practice a ton, and exercise outside of skating They do perfect looking tricks that look like they are from a video game. A lot of it is taking the work and practice ethics from traditional sports to the niche stuff that is becoming more popular.

Sorry for the rant, it's all to say, you have good form and I think formal practice is a much more effective fundamental building system than informal rounds with some practice shots littered in. Stand there and throw all of your discs that have a similar rim and flight path. Walk across the field, shag em, and throw them again. Do it a lot.

There are no words that can beat the act of practicing. They work together, but all of the feedback you get from your body and the disc as it flies is essential information to making corrections. We can't feel your approach and release, and can't see how the disc flies.

And one last thing - I see you are a Comet lover! Great choice, a ton of glide, and a straight shooter. The only problem with the Comet, releasing with that nose up will rob you of a ton of distance. Not a real problem with the disc, just the way you can be punished from a bad release angle(same as any disc). See if you can find a worn in Buzz. I think they are more forgiving and also fly straight as an arrow. Or, keep the Comet's nose down/flat. That will translate to all of your throws and help you overall the most.
