I will admit it was a bit of a dark piece, but I was going for a psychological horror. Not sure if I achieved that. I've only been in creative writing for about a month now.
A flood of memories broke the seawall that protected my mind
That quote was just my own writing without any inspiration from any book.
I was leaning more towards a larger park,but I'm positive the real Gulliver's Kingdom in Japan is not a massive park. Your assumption of Trixie's age is nearly there, she's more towards the age of 10. The resentful part I will admit was a bit of a foggy section, I wanted to show that the mother was spiraling towards insanity.
Criticism always welcomed, it does make me better in what I do. I wrote the story practically in four hours.
