@KaiOlim Thank you for giving me the opportunity!
I'll just be giving some tips here and there, but it's mostly my opinion.
Your descriptions are very simple. The advantages of that are that you won't stray off course, and your plot will make more sense. However, you might find that it feels distant, like you're watching behind a fogged glass barrier.
Maybe try rewriting each paragraph (yes, always rewrite, never edit) with incomplete sensory description -(It was dark. Impossibly so. Or maybe she just couldn't see. She froze at the thought. Was she blind? No, that couldn't be. There- there! A light! She could make out dust dancing in a sunbeam.)- or adding onomatopia before showing how she reacts (Thud. She jumped. What was that?)
And I notice your sentences are sometimes phrased like CNovel translations, with the Chinese grammar rules that allow 'What a dumb dog, he can't even stand!' In their place, you can use semicolons; they elaborate on an idea/statement made in the first place.
You've chosen to write in third person, and it's created a small void between reader and character. You can perhaps write in first person, then paste third person pronouns into the text. If that doesn't feel right, try stretching out your scenes with descriptions.
Again, your words are very simple and factually stated, so your readers may be unused to a switch in writing style, and it's easy to oversaturate text. I do believe that it's the most suitable strategy for you that I know.
To help with grammar and punctuation I've downloaded Grammarly as a browser extension, although that's just a suggestion since it does get in the way of digital visual poetry.
I apologise if this isn't what you're looking for, but I hope this helps, and I wish you good luck on your journey!
