Life In 19x19

Hi! My first game ever here so be gentle please

This is a recent game i played on kgs where i felt i missed some big points and that i was alittle slack in my play (as black). Would be nice if i could get some pointers where i strayed from the right track.

Thanks in advance and feel free to guess the strength of the players if you want

[Edit] I won on time just before the beginning of some boring yose but i was slightly behind then i think

B move 113 was risky; hane on the other side (N6) would be safer. B had a chance at move 119 to capture some W stones: atari at N6 followed by squeeze.

Move 81: B should simply capture. Sente / gote exchange here is big.
