Congratz Mirek, nice return 
My solution was completed too late, but i published, because a good example for NISS.

D’L2D’F2U’R’LF2D2RLF’R2L’B’R’LUR’FR’DB2RL (25 moves)
NISS solve,
inverse scramble with premoves L2D,
R’L’B2D
switch to normal scramble,
D’F2U,
(this is my best start, but the continuation a hard case)
switch to inverse scramble,
RF’RU’L’RBLR2FL’R’D2F2L’RU2, one move cancel.

What a suprise Mirek! And with a nice 21-move solution!
I found a similar F2L, same corners but different edges, and could't solve this LL in 13 moves or less.

In a Spanish FMC page I usually participate in we had this scramble:
D' F2 L F' D' R U' B' U' L' F2 D' R2 D' L' B R D2 F L' B U R2 D2
My skeleton was something like this:
2x2x2: F D' B' L
2x2x3: R F U F' U2
EO: F2 R' D'.F2 D
Leave 3 corners + a twisted one: R F R2 F R F R F'
OK, I inserted R B R' F2 R B' R' F2 at (.) to solve a corner and take the twisted one out of its place. But now I can't insert the 3-cycle that remains efficiently, so I just solved it with an A9. What would you do with my skeleton?

You may want to take another look at the twisted corner cycle, the first one I found cancels 4 moves instead of your 2:
2x2x2: F . D' B' L
2x2x3: R F U F' U2
EO: F2 R' D'.F2 D
Leave 3 corners + a twisted one: R F R2 F R F R F'
at . insert B' U2 B D' B' U2 B D to cancel 4 moves
I did not check further

I found a 7-move 2x2x3 for FMC #361, and figured it was probably optimal. Actually, the optimal 2x2x3 was only 6 moves: D' L D2 L2 F' D2. I had also found an 8-move 2x2x3 (U' L' R D2 U' B U L2) which was actually optimal for the DF 2x2x3 block. However, I couldn't find a really good finish for either block. The best I could come up with was 30 moves. Anyway, it doesn't look like anyone else found the 6-move block either, or else found it but didn't use it.
I note FMC #356 had a 5-move 2x2x3 block.
And my congrats too on the Mirek-ulous 21-mover.

L' D2 L2 completes the 2x2x3 much more efficiently than L D' U' F2 U.
(An interesting continuation is D F2 (finish cross) F D2 F2 D2' F (3rd slot) leaves only 6 pieces to solve.)
F2L slot 4: 8 moves is a lot of moves just to solve 2 pieces.
OLL: First of all, if you orient edges as a separate step, you should probably be looking at COLL/EPLL instead of OLL/PLL at the very least. But learn about other FMC techniques for finishing a solve.
Second, you ought to know alternative ways to do OLLs, and how symmetry and inverses can sometimes allow you to do do something a different wayif/when applicable. For a sune, the inverse mirror alg, applied from the correct angle can be used in place of it. F D2 F' D' F D' F' not only gets you three moves canceling with the previous alg, but leaves a J-Perm instead of a G-Perm. Solving J-Perm F2 U F U' F R2 B' D B R2 D2 gets another canceled move. This rather obvious alternative to have tried alone shortens the solution by 6 moves!
Usual tips: Read the FMC guide thread (and browse this thread too). Read the Wiki. Look at other people's FMC solves.

New PB, 33 moves. I got this scramble while doing an average btw, had to FMC it. Someone really good could probably sub 25 this.

I found an optimal solution for 2x2x2 in Weekly competition 2011-37.
Scramble: R2 F' U F R U2
Solution: z' y' F2 U' L' U' L U2
Of course the best time in 5 attempts.

The scramble from "Swedish Championship 2011": B' F' R2 D2 F' D2 F' U2 F U2 L2 R B D U L F L' R2 D U (21f)
Must have been a pretty easy one since the two winners (Simon Westlund and Henrik Buus Aagaard) had 27 moves, plus after that there were three 29 move solutions.

Unfortunately 30. Had 4 corners left after 18 moves but no time for decent insertions and ofc I missed the start that "everyone" found.

LOL scramble...
Within 3 minutes:
2 move cross
or
5 move X cross, 2 additional moves build two pairs...
Gotta look into this when I get home from work!

My first try:
2x2x2 block: L2 B L R F'
Pseudo 2x2x3 block: L U' B' L2 U
And more:
2x2x2 block: U2 L2 B L R U F'
Pseudo F2L minus 1 slot: U2 R' L2 U L
All but 3 corners/edges: U' R
(or All but 3 corners: U2 F2 L F L' F U R)
Should be 26~27.

From Swedish Championships 2011:
Scramble: B' F' R2 D2 F' D2 F' U2 F U2 L2 R B D U L F L' R2 D U (21f)
L' R' B R F' (5) x-cross
U' B' U2 R' U' R . (6(11)) 2nd pair prepared for 3rd.
B' L B2 L' (4(15)) 3rd pair 4th prepared
U' L U L' (4(19)) F2L leaving 3 corner cycle
insert at .
R D R' U2 R D' R' U2 (8 canceling into 7 moves)
Correct layer:
B (1)
So solution is:
L' R' B R F' (5) x-cross
U' B' U2 R' U' R2 . D R' U2 R D' R' U2 (13(18)) 2nd pair prepared for 3rd.
B' L B2 L' (4(22)) 3rd pair 4th prepared
U' L U L' (4(26)) F2L done OLL skip PLL forced.
B (1(27))
Simon's solution had a different insertion but at the same place in the solution, I don't remember the commutator he used.
The obvious 29 move solution would be to do the 3 corner cycle in the end with the common 9 move speed alg.

Might as well post my solution:
L' B R F' [2x2x2]
L U' B' U [Peudo 2x2x3]
Switch to inverse:
L U [2x2x3+EO]
B2 L' B2 [F2L-1]
L' B' L B L [Leaving four corners]
Which gives this skeleton:
L' B R F' L U' B' U L' B' L' B L B2 L B2 U'.L'
.=U B' U' F U B:U'*F'
:=R D' R' U2 R D R' U2 (Really stupid; *=U2 F D2 F' U2 F D2 F' cancels one more move)
L' B R F' [2x2x2]
L U' B' U [Peudo 2x2x3]
Switch to inverse:
L U [2x2x3+EO]
B2 L' B2 [F2L-1]
L' B' L B L [Leaving four corners]

Found this one too, it was really just a straight forward continuation of the X-cross + 2 pairs I already posted yesterday.

I just managed an 11 move F2L-1 with 2 oriented edges but cannot find a good ending.
Generator: F' R' F2 R2 B R' F R' D2 L F L2 D2 R U' (15f*)
Yeah, this already tells something...
Took me 21 moves for a final 32 HTM.
Looking forward to your solutions!
