I thought that a 17 move start for 2x2x3+3rd pair was great...
17 moves for this is definitely not bad, but it's not great either. I have gotten a 13 move F2l twice!
Also, I ran your solution through Cube Explorer and this is what I got:
Scramble: B2 R2 D' L2 R U L2 F' U2 L B' L2 D' L B2 D' F D'
First part of your solution: R D2 R' D L' U2 F' L B' L' F2 B' R B R' B' R U' B2 U
and then your final 12 moves turn out to be optimal R' U2 R U' R B' R' U' L' B2 L B2 and that is the only way 12 moves could be reached (next was 14 moves).

Thanks to Arnaud for explaining the 5x5.
Wow, very consistent! I hope you have a lot of fun.

my first try at this (at the week contest)
not that bad, I think
Not bad at all for a first try. I hope you like it enough to try it more often. I examined your solution and found a really easy cancellation (insertion) within 2 minutes:
y R D' L U' F' R' B (7) - 2X2X2 and a pair
L' U' L R' F2 (5) - 2X2X3
y (R2 F' D U' R2 U D' F' R2) R U2 R2 F2 R2 U R' U F' U' F (11) - finish F2L

Solution:
F' R F L2 D' F B2 L U L' U' R B' U2 B' U B R B R' B' R' U' L U R U' L' U2
Explanation: Do premove U to see what happens after the 2x2x3 block. The pre-move cancels out nicely in the end
F' R F D' F (5) would create a 2x2x2 block, but no good continuation. By adding an L2 move a nice continuation does exist.
F' R F , L2, D' F B2 R (8) would create a 2x2x3 block with an L U L' U' B' U' continuation, but no good continuation from that point. By changing the order slightly a very nice continuation does exist:
F2L minus 1 edge: F' R F L2 D' F B2 L U L' U' R B' U' (14)
Final edge + Last Layer edges: U' B' U B R B R' B' (21)
Corners Last Layer: R' U' L U R U' L' U (29)
Undo Pre-move: U (still 29)
I tried to use insertions for the final 3 corners, but I couldn't find anything in the 10 minutes I had left.
