Great work with the plot, the story is super fun and easy to engage. I love how you present the character in a peculiar situation right at the begging but without the world building getting cramped that's not easy to do. Your alternative world situation mixed with elemental powers its very entertaining and with a good, well defined dark side.
The things I believe you can improve are mostly the descriptions, sometimes they can feel unnatural, when your character goes on like there is a list of things they need to describe it feels very obvious that you are doing it so the reader knows what is there, I think you could try to be more subtle about this specially because you use first person POV. Why would your character take notice of something they see every day? Give them an excuse to mention something about their surroundings in passing, and try more general descriptions. Try asking yourself if its necessary for the setting or if you can skip it.
Also the transitions in the mood of the characters can be a bit abrupt. You need to be very clear about what and how is the emotion of a character changing. You can't just tell your reader that A say something mean to B if the dialog itself didn't read as mean. Try giving a bit more of an explanation at the characters emotions.
Hope you find something of that helpful and that I made myself clear!
Keep working hard!
