I had another chance to look.
Move 34: Probably too far.
You may be able to get away with the 3-space extension at R7, because your right side group is moderately strong vs the black upper right corner.
But your lower left group is weak when compared with his lower left group, and the invasion at H3 can hurt. If he plays it, and you defend K3, then he scoops out your eye space with D2. ( D2, C2, E3, E4, F2 and he is connected out )
Also R7 approaches within two spaces of an enemy stone; K3 within one space.
36: D11 is looking a little weak. It might be better to play someting like D9 or D8 or C10.
42: D11 is definitely too weak. You need something like B14 or E8 or H12 now. ( But O15 is locally a good move )
58: You don't have time for this. Have you considered what happens to your long eyeless group if he plays L10?
59: He doesn't see it. I think that you dodged a bullet here.
62: This is aji keshi. Save it for a ko threat.
You own C5 in the endgame. It is about 15 point sente for you, 1 or 2 point gote for him. You will have half a dozen opportunities to play it before he has one.
This is an important concept to learn.
76: Good move.
78: Huh? This undoes 76. You could have connected K7 to the corner group.
Now you have two eyeless group in the middle of the board.
82: What do these stones do for you? It would probably be best to abandon them, and invest your move elsewhere with a group that shows a better return.
Overall, not a bad game for 10K.
Most of the mistakes that you made were simply errors of degree, choosing a slighty lesser move. These only requires refinement. But 62 is an outright mistake that suggests that you are totally missing a concept. Check out
