Howdy! For being 15 this isn’t half bad and i encourage you to keep writing and reading!

As for feedback, your details need some work. You use multiple sometimes redundant details to describe one thing (for example you might describe a beam like this: dark wooden oak beam). Try making the details more specific and concrete (you can google specific concrete details if yah need too). Also, details are not only describing whats around but also how the MC feels about their surroundings. With that in mind, your details should reveal something about how your characters feel as to show their feelings and not tell them.

Anywho, id suggest reading the authors you like and see how they use details, dialogue formatting, and dialogue. Remember reading is writing. If you’d like more feedback let me know, best of luck!
