Hi, HollyMichelle!
When I do a session review- I stress on a certain thing if I feel unsure about it-say push/fold when eff. stack sizes are 5bb or less, bubble play, blinds play, steal-resteal with 13-20 bb eff. etc. or do a whole session review for say, HH that I finished 1, 2, 3 or bubbled out. I think doing a good mix of these both is helpful. Marking hands is crucial and I think as for this moment, this is most of what I do to review my game as I am already familiar with the basics. There is always room to improve though, so maybe I need to go through my detailed analysis as well.
If you master bubble and ICM concepts of 9-player SnG, you should really move up the stakes pretty quickly as postflop is reduced anyways + most FR players either underestimate it or are just careless or bad about it. Improving your game is a good balance of a few things, so adding some videos, articles will also be in a good help for you. Will give you few more ideas and alternative lines as well. I watched some cash videos last month and I can assure you, they were really helpful.
Cheers!
