At move 65, connecting your cutting stones at L8 looks like a must to me. You need to keep white disconnected, otherwise you can't continue to fight in the center. After white captures the two cutting stones, it seems that Black didnt really gain anything from the attack that started in the upper right.
The territory vs influence game you play looks reasonable, in this modern era.
B25 may look like a reduction move but it is single minded. White doesn't even have to respond and is happy to play in the open corner. Instead, if you play a territory game, make an enclosure in the upper right, to compensate for White's sphere of influence forming at the bottom.
B33: why pincer wide and not tightly? White is strong there, so stay away from him.
This starts the middle game fighting.
B35: White plays close to his own thickness. You have a few options now: you can sacrifice the pincer (by kicking the approach stone, or make a one space jump descent), or you can continue the attack (by jumping out or keima)
B37: When you kick at 35, then jump, you do attack but in effect you come under attack, since there is nothing for you to do at the other side
B45: with W43 boshi, White plays a classical attacking move which AI teaches us to be seldom rewarding. You do well moving out.
B53: misses a chance to cut and take the lead. Lizzie says it's a 20% error.
After that, the pseudo squeeze makes the game go downhill and Black never really recovers.
General recommendation: look for moves that do 2 things, not 1 thing.
