Hi there, I am writing this post to get some feedbacks and advice from more experienced players because I feel I am really stuck in my game, and I am oblivious on how to move up.

I am an italian player, I play on PokerStars.it. I have been playing sporadically for years, but I have become a much better (I think) player in the last months.
In the last 6 months I played many MTTs and I got great results. I won several tourneys, making around 6k, and it felt really good cashing out some profits.
While I do not believe to be a great player, I feel I definitely beat the levels I play, which are MTT small stakes (5$-30$ buy in).

One thing I wish to do, and I don't know how, is to study my game, and review my hands and my tourneys. I think I do have a good grasp on the game's fundamentals, and I am becoming pretty good in certain spots, but I have no idea how to approach the game AFTER I played.

What I have been doing is to select the biggest hands I played in a tourney, and review them using Poker Stove, Combonator, ICMizer and similar softwares.
I basically consider my ranges, opponent's rages, and I calculate odds and EV in a specific hand, trying to determine if I played well or not.
I don't know how to do more than this.
Can some of you help me in finding a better, more structured approach to hand analysis? How should I do it?

Thanks a lot to whoever would take the time to answer me.
