I am currently in the works of a Leaugue of Legends fan novel based on what a match in the rift would look like from the champions' perspective. Go ahead and check it out. As of the posting, i only have the prologue done and edited.
I think this would be very helpful in helping you visualize it more: https://www.youtube.com/watch?v=vzHrjOMfHPY Your writing so far is descriptive, but there isn't enough for me to really give helpful tips on anything. I like how you slowly introduce the characters instead of straight out saying "Hey, I'm Kindred, look at me~!" or "Oh look, it's Katarina!"
The only suggestion I can really give is to not draw out some of the descriptions. The way you limn the fights around the Jungle seem somewhat scattered and gives the impression that you're pushing yourself to make the writing sound more poetic. Just write how you feel sounds the best. Other than that, it all has a really nice feel to it, and I wish you the best of luck!
