Review request of 9k vs 4k

I was black (9k) and lost this one by 11.5 points. It was pretty complicated game with a lot of weak groups running from the right side of the board, all the way to the left side. Except for the mistake in joseki sequence in lower right corner I feel like I played my best.

I feel like there were a few moments in the game where I could be a little bit more aggressive in attacking the weak groups, or maybe there was a beneficial sacrifice possible, or even just tenuki-ing and taking the biggest point on the left side would have cut it.

Thanks in advance for replies.

You did a good job with this game, but there’s plenty of room for improvement. The biggest areas are shape and recognizing weaknesses. See the review below.
