Your second game was better.
You had no really big mistakes. The worst that I could say was that you made a lot of unduly conservative moves, strengthening yourself instead of going after the opponent's weaknesses.
Just be a tad more aggressive and you will get several stones stronger.

Usually in response to a pincer, you either run out, tenuki, or counter-attack one of the pincering stones. See variations.];W[df];B[dc];W[ec];B[db];W[ph];B[ed]C[JB: Good move! White should have played here last move. W is out of his joseki book and has no clue how to proceed in the corner. You apparently know better.];W[oc];B[nq];W[dl](;B[pm]C[JB: This feels a bit small, especially in response to the optimistic, expansive play of white. W has weaknesses. See variations];W[fp](;B[en]C[JB: Very risky. The keima can be cut. The general idea of moving out into the center is good, but there are safer ways to do it. See variations];W[qk]C[JB: This is an example of a much safer keima ( ogeima to be exact ). Even though it stretches more, it is safer because its backside is against the edge of the board.];B[ql];W[pk](;B[rl]C[JB: This looks premature. It is almost a yose move. There are bigger places to play. See variations];W[fd];B[ee];W[fb];B[eb]C[JB: What does this do for you? OK, eventually you will get get one additional point around D19 because of this.
But did you have to do it now? What happens if you don't? Will he play E18 himself?
Of course not. It would be small and gote. He can't play this util way late in the game. Save moves like this for ko threats.
Late in the game, when the biggest kos are half a point, and big ko threats are not needed, then maybe you play it.];W[fc];B[de];W[gf];B[ef];W[rk];B[dg];W[gn](;B[el]C[JB: One-on-one contact moves are usually defender's moves. He has two weak groups, and you are cutting between them. Don't let him strengthen himself by allowing a small one-on-one fight. Think big.

There are many other options available. See variations.];W[co];B[cp];W[dn];B[eo];W[jc](;B[gl]C[JB: Attacking these stones is not a bad idea. But you are coming from the wrong side. You have a strong wall. He wants to run away from your strength.

He is starting to enclose a large portion of the board. See variations];W[jg]C[JB: Ouch!];B[ok];W[oj];B[nj];W[nh];B[oi];W[pj];B[ni];W[oh];B[mh];W[pi];B[mg];W[lm]C[JB: See what he does?

BTW, there is an important idea in the comment to move 27. Make sure you read it.
