There is this website that can analyse your games here. https://mjai.ekyu.moe

This site is pretty helpful in analyzing your games using an AI mahjong program: https://mjai.ekyu.moe/

You can use Akochan to review your games. It isn't perfect and it doesn't give you a reason why your choice is not the best like a chess engine.

There are plenty of things you can do on your own to become a better mahjong player, though. Log review your games with an AI like Mortal or Naga, or with stronger players. There are also a couple of English translated higher level resources for improving your mahjong gameplay, like Uzaku's guide to tile efficiency and WWYD problem books, and Statistical Mahjong Strategy.

This would be an interesting one to run through Mortal.

This is all just what I would do though. If you want a more definitive answer you can throw your game log in to an AI like Mortal or akochan and they'll tell you how strongly they feel about a riichi.

There is a website that can analyse your games and give you what should be discarded based on EV, but its currently under maintenance (https://mjai.ekyu.moe/), if you don't want to wait for it get off maintenance you can just download the program to analyse your games but its not very user friendly: https://github.com/Equim-chan/mjai-reviewer
