Towards the end, the white group on the right side died because he misplayed the tsumego. I believe it was alive unconditionally, but can anyone see if they are able to kill it? If anyone is willing to provide an overall review for black, that'd be great. Thank you for the review.

127 at S12 should kill unconditionally. 131 should hane on the other side instead of blocking. |

White should play 114 at P12. So can Black play 113 at Q12? |

Regarding 3rd line stones, there is saying in Japan that 4 dies and 6 lives (5 depends on who has sente). So you should strive to make a 3rd line of 6 stones or make a line of 5 stones+sente, if you want to live within an opponent framework. |
