Yes for surrounding describtion (which I first tried myself but was terrible) and fixing grammar proof reading.
I'm not going to say "Don't use it, Ai is stupid." because I'm sure you'll hear that a lot, but it's incredibly obvious that you are using it. If you really want to continue writing, it should read like someone wrote it. It currently has too many repeating words, and full of bad punctuation. It's not bad, the story isn't bad don't get me wrong. It just reads very bland, and that's mostly just the Ai. I felt like I was reading the same line over and over in a few sections. I had to stop and reread it to make sure I wasn't.
Using Ai to help you is fine, it's a tool, but don't post exactly what it says. Take it as inspiration, and write it for yourself. Like copying your friend's homework. You want the same answers, but don't write it the same exact way or you'll get busted for cheating.
If you want to get better at descriptions, read more books, and I'm not saying this to be rude, but start with kids books. The reason being, is because kids books are a more description style of writing... "this happened, then that happened, in this location, with such n' such event going on around them". etc. There isn't much dialogue like there would be with young adult books, or teen novels.
Practice descriptions with short paragraphs on your own time. Look out your window, or just around in your room, and just describe the scenery as if you wanted to tell someone what you see. Start with the 6 senses.
Sight - What you see
Smell - What you smell
Listen - What you hear
Touch - What you imagine things would feel like
Taste - What you can imagine tasting
Proprioception - How you carry yourself in that environment. Movement, Stance, balance, understanding the space or world around you. How you interact with it.
Imagine the floor is lava, create a character, and ask yourself how would you get them from one corner of the room to the door. Imagine it. Give all the details you can.
Or if you're looking outside: Is it a hill you can roll, or tumble down, or a cliff, that if not careful, could fall? Is it a normal backyard to play kickball? a forest to adventure in? A pool to swim? A beach? a mountain? A zen garden to meditate? I don't know what your backyard looks like. It could be a castle in some private island for all I know. describe that.
The big thing is, Ai doesn't understand grammar, or paragraph structure. You need to study those things on your own. Ai will insert random commas, or giant bars in random locations, which yes, sometimes it's a fair place to put them, but it'll do it so often, it'll just make the paragraph look like a mess. Learn to use punctuation, it doesn't need to be perfect, authors write in various different ways. In truth it's very easy. your main three are periods, commas, and semicolon. once you understand these three everything else is whatever..
The most important-important thing is finding your own writing style. Leaning heavily on Ai will look, and read different every time in every paragraph. Small things can pull a reader out of the immersion, and make them not want to continue.
Again, I'm not trying to convince you to stop using Ai, I'm just giving you my own thoughts which you can toss aside at your own accord, it doesn't bother me if you do. I do recommend using a tool for what it is, a tool to help you, not to rewrite, or do the homework for you.
Practice is hard, and learning new skills is difficult, but it also does make you a better person for it in the long run.
Your story is fine, it just needs a personal touch. Ai can't give that sense of feeling, or emotion.
