R2 U B2 U F R' B L R F D' B U F' D2 U B' U
In total there were 10 Rotations during F2L including the Cross.
You want to keep rotations during F2L to about 2.
The Cross:
Your Solution: R z' L' U L x' R U' x' U x U2 L2
When solving using CFOP, you will usually want to start with holding the cube with the white center on the D-Layer.
It looks like the way you solve the cross is by solving it piece by piece.
Try setting up the cross pieces so that when you solve one, the other one is already at an easy setup.
In my solution, I see that 2 of the cross pieces are already in place, just misoriented. After that, I see that when I solve those two cross pieces, the White-Blue edge will have a one move setup to match relatively with the other 2 cross pieces.
Current Partial Cross: z2 L' F' R' L'
One cross piece remains, and has an easy setup, by manipulating the D-Layer so that pieces can be more easily solved, as long as you restore using D or u moves.
My Solution: z2 L' F' R' L' D L' u2
F2L-1:
Your Solution: z' (R U' R' U) (L' U2 L) (U F' U' F) (U' L' U L)
F2L is harder to explain how each CE Pair can be more efficiently placed into the correct slot.
Looking through fast solvers solutions, trying different ways to pair up the pieces, and possibly learning algorithms for each case (

My Solution: z' (U R U' R') (U L' U' L)
F2L-2:
Your Solution: y' (L' U L) y' (U R U R') U' (F' U2 F) y' (L' U L)
My Solution: y' (R U R' U) (L U L')
F2L-3:
Your Solution: (R U R' U') y (F' U' F) (U' L' U L)
My Solution: U2 (R U2 R') (U' R U R')
F2L-4:
Your Solution: (U R U R') U2' y (F U2 F') U2 y' (R U' R')
My Solution: U (R' U' R' U') (R U) (R U) R
OLL:
Your Solution: U F R U R' U' F' U' R U2 R' U' R U' R' U R U R' U R U' R' U R U2 R' U'
I currently use 1-Look OLL, but you can manage Sub-20 with 2-Look OLL.
My Solution: U R U R' U' x D' R' U R E z'
PLL:
Your Solution: U U U x R' U R' D2 R U' R' D2 R2 x'
U U U' U M2' U M2' U2 M2' U M2'
It is still possible to be Sub-20 with 2 look PLL, but by the time I was averaging 25-30 seconds, I had finished full PLL.
My Solution: U l2 D2 R U R' D2 l F l U'
Sorry, I can't make a video as I don't have a channel or things to record with.
