[2443] There are no animals here but us

Hello, I'm a new writer wanting to learn.

This is part of the first chapter for a fanfic I'm writing for Qiang Jin Jiu with a Hunger Games Crossover AU. It doesn't need any prior knowledge of the former work, but does assume some Hunger Games familiarity.

Some questions:
- How does the structure of the chapter so far feel? Is it clear which scenes are flashbacks and which scenes are the present? How is the pacing?

- Do parts of it feel clunky (if you get what I mean)?
- As a new writer, how should I approach learning writing?

All feedback is very much appreciated!!

Note: [resubmission due to concerns with leeching]

Hello, I received a message about my previous post due to concerns with leeching, especially since it was close to 2.9k. I would love to give another critique but I'm honestly beat at the moment. Since it was mentioned over 2.5k the demands for critique increase exponentially, I've cut down my piece to 2431 words. Let me know if there are any more issues.
