A good thing common in these throws is that you have consistency. The throws didn't seem to be too different from each other in many respects. The thing that varied the most was nose angle and that I think should be your first priority to fix more on this later.
I like that you have a large follow through in the range of motion. It protects you from injuries. Just like pivoting on your last step and stepping through the throw with your left leg after the rip.
I also do like that you are bending your right knee well in the plant(last before rip) step. A good thing too is that you bend your waist forward. These help with getting the nose of the disc down. The nose being in this case the front of the disc. The snag is that you have too little bend forward at the waist at the rip. The center of your chest is behind your right knee at the rip. This in part leads to the fact that the disc leaves your hand so that the front of the disc above horizon. This creates huge amounts of drag and slows the disc down and raises it high (almost or fully) stops the discs and it stalls to the left. You lose major distance this way.
Even more important is to read to grip it to rip it article on the main page. You don't bend your wrist down. This is the number one cause to having nose up angle on your throws. Not having the wrist down also creates off axis torque which kils distance a lot and makes flight lines way more flippy and understable than the disc actually is. Please do use the search function on this board to search for OAT and off axis torque. Lot's of gems...
Your hand is lower at the reach back and higher at the rip which makes the nose up problem worse. Try to keep the height of the disc constant through the throw.
You don't really seem to twist your hips powerfully and quickly. It seems that you just turn by the momentum of your steps. You should also try to accelerate the arm after the disc passes your right side very quickly. This requires slow arm speed up to that point. Your arm should be straight and pointed at the target when the disc leaves your hand.
There are other small things but you have a lot to train in these areas and I think that you should get these basics right before honing the less important things. Since you have a video camera I think you ought to get the basics to work first and then post a new video for the rest of the goodies
With luck you've gotten the rest right training for these basics.
Good luck and have fun in training. You should see a lot more distance fairly quickly once you get what is written in the articles and on this board. And apply them to your throws.
