Game review 18k vs 16k (new ranks)

I lost this game by 4.5 points (which i consider close) but i feel like i was behind for a lot of the game. Would be interested in an opinion on how early i was behind and where my small/slack moves were.

Any and all feedback gratefully recieved.

I put some comments under https://online-go.com/review/263768. Take them with a grain of salt, as I’m also a rather weak player.

One thing which happened twice in the game is that you peeped into a keima without cutting. This only helps the opponent fixing his weaknesses. There is some more explanation about that at http://senseis.xmp.net/?CuttingTheKeima

Thank you for taking the time. I look forward to reading your thoughts.
