Life In 19x19

In this game on OGS, I got off to a bad start while playing an unfamiliar sequence in the bottom left, and then continued to lose ground on the right. By move 92, Black just has to play safely to wrap up the game, but he gave me a chance and we ended up with a semeai. At move 143, I read that I was ahead, while at move 157, I read that I was a move behind, but then I think R12 gave me a chance, and I ended up winning the race.

So I'm looking for comments on any part of the game, but especially where either of us went wrong during the semeai.

I added some comments in the attached.

I'm a bit of Luddite, so I have no idea how to get the attachment into SGF view. (edited - may have achieved success)

Move 48 was an overplay - my comment went AWOL on this move.

Btw black's a she

My apologies: I'm not very good at avoiding gendered pronouns when talking about my opponents.

And dmrwc: thanks for the comments, you've pointed out a lot of the moves that are exactly my type of blind spot.
