Very fast shooting and relying on quite a bit of luck for the next shot in that video. Does not seem like there are lots of plans for shape, just sending the cueball in the general location of the next ball.
In the third rack you had that cluster, took ball in hand, and then shot quickly without planning where the cueball or next ball were heading and ended up hooked. You could have shot the 1, then the 2 and used that to break up the cluser or made sure you hit the 2 on the right side and speed where both the 2 and the cueball went to a clear area.
Also quite a few mistakes in spin and speed. Like here
https://youtu.be/JyulOjm6gew?t=9m36s there is no way you should end up going bellow the 6, center ball with a tiny bit of left or 1/2 tip draw will send you to the rail and back out for the 6 in the corner. Running into balls quite a bit. It's OK to do that at times when you don't have a choice, but it seems like you were doing it because you could not control the cueball to avoid them.
This rack is almost all luck
https://youtu.be/JyulOjm6gew?t=10m57s it looks like, you almost got hooked (I could see the table roll save you from being behind a ball), ended up on the rail a few times, then got lucky and hit the 6 for position on the 7 then had almost ball in hand shape to get to the 9 but looks like you used reverse and killed the cueball, unless that rail is dead.
I'd give you a C+.
I don't mean to be harsh, but you really need to work on planning for position and execution of the position better, you play like someone that learned to pocket balls from just playing a lot, not from studying and playing good position.
I'm sure you can beat a lot of bar players, but a B player would probably beat you 75% of the time in any race over 2 or 3 without you planning out position better.
