On one hand, you look like you have a good idea of what you want to do, on the other hand you look like you're going faster than you can handle. For example, in the first clip of the video, you panicked when flying under the tree and tried to gain control and ended up crashing into a window because you were going so fast and couldn't correct your path

If you want to freestyle, I would recommend lowering your angle. Yes, you will go slower, but you'll also have a lot more control and precision. I have a buddy that's extremely good at flying freestyle, the dude is insanely good, and his angle is 15°. His precision is on point and he has total control. He says freestyle angles should be 15 to 25, but personally I think 25 is still too fast.
