really hope I got the scramble and solution right haha
You can use alg.cubing.net to check your solutions, and it makes reconstructions easier to view as well. It took me like 10 seconds to copy/paste your solution there and see that you forgot a U2 at the end but everything else is fine (here's a link for your solution specifically)

share your method please....
thats ADVANCED method , man ....
First, I found this 10 move solution for corners:
R U' F' // CO
R2 D2 F2 L' U2 L F2 // CP
Then, I switch to inverse scramble and found this for CP-moves:
(F2 L' u2 R F2 d2 R2) = (F2 L' D2 R B2 U2 R2) // corners minus 3 moves, and many pairs.
Then, I switch to normal scramble with R2 U2 B2 R' D2 L F2 pre-moves,
R D' R' // all corners and many pairs,
B L B F' D' B R B' L R' U // last edges.

U F2 L2 U B2 L' U' D F R //DR (10)
D2 R2 U2 F2 U' F2 U' //Corner HTR (7/17)
L2 D2 L2 D' R2 L2 U //Finish (7/24)

tl;dr I try to do what Attila does.

This is an example of domino reduction found by orienting corners first, rather than edges. One clear advantage of this approach is that one can immediately see if corners are easy to solve after CO, which is the best heuristic to determine if a DR is good or not. The main disadvantage is that it is hard to go from CO to DR in practice.

At first I tried this CO:

U B2 R2 D F (5/5)

And I noticed that the corners were somewhat easy to solve (or rather easy to HTR, and then solving them is trivial). So this is a good CO to complete to a DR, if one wants.
So I changed the CO slightly to improve edges:

U F2 L2 U * F //Same CO, slightly different (5/5)

And then inserting B2 L' E' L at * gives a DR (with nice corners).
Rewriting the solve so far for clarity:

U F2 L2 U B2 L' U' D F R //DR (10)

Then it was easy to almost-solve corners:

D2 R2 U2 F2 U' F2 U' //Corner HTR (7/17)

And finishing it off:

L2 D2 L2 D' R2 L2 U //Finish (7/24)

Next scramble: R2 L' B' U L F' D B2 L D2 B D2 B L2 B2 R2 F' D2 L2
