@ItsHerobrine2 Hi there, writer! I'm so thrilled you enjoyed my work, and thank you for your kind comments ♡
I'm not a professional at all lol but since you asked for my advice I'd say a good place to start is to read a lot of the kind of stories you want to write yourself one day. The more you engage with the kind of writing you want to "imitate," the more you'll find yourself writing like that. The flow of the story will come to with practice after some time.
Also, don't be too harsh on yourself. You learn to write better by making mistakes. So let yourself write stuff that you think is bad sometimes, but then go back and reflect on why you don't like it so that you can figure out where to improve.
Happy writing!! :)
