I started with Akuma, so won’t say it’s not suited for beginners. But I read, watched a lot ! And I was really motivated to learn the background basics of the SF games. And it took years to be able to maintain a certain level. I also had offline friend to play with the first year. Helps to get some fun unlike the online constant blow ups.
The thing is though, at you stage, you wont really improve from people feedback much. I always said that. You can’t understand really before you reach a certain amount of game experience and before you, by yourself, start feeling the issues you face. And start to seek solution to these one by one.
Execution will be on your own training course for a long time.
Then there’s basic safe universal game plan against scrubs. To anti air, and punish unsafe shit. (The punish to find on every other character unsafe move can take a while as there’s very tricky one abuse-able unsafe moves online).
Only there, you can force opponent to play smart and according to the matchup.
That’s when and only at this point if you can apply the above things fine, you will have to fight better opponents that wont give you much chance to score punishes. You can then step up your game with spacing, reading opponent next move, footsy, whiff punish.
And in all these area, people feedback is usually the only way to go. Because there’s not much you can figure out yourself. Unless you watch a lot of your own replay but most people don’t, I don’t. But I no more care about leveling up. Will be a scrub forever
