Excerpts from "The Maretian" (Friendship is Magic + The Martian crossover)
GalanDun for Young girl in Spitfire's dream.
In Spitfire's dream on Sol (Martian day) 450, some human kids run up to her and speak with her. Spitfire knows about humans from the videos and pictures she has seen from Earth, sent by NASA. While she struggles with English in reality, in her dream, there is no language barrier, so the kids speak the same language as her. Spitfire has physically languished on Mars, not being able to fly or exercise much. Her depression stems from the fact that once back in Equestria, she isn't as strong as she used to be, and she thinks she's worthless. There are four kids: A young girl, a young boy, an older girl, and a girl older than that - a teenager.
And then a group of kids- human kids, with human clothes, with incredibly familiar human faces, running on the streets of Canterlot- ran up to her. “Hey, look!” shouted the youngest girl. “It’s a pony!”
Young boy: That's a Pegasus!
“Wow!” the girl said. “Can you fly, Ms. Pegasus?”
This sounds more like a teenage boy than a "young boy" to me. I'm thinking something like, 7-12 years old. Can you do a younger voice? Here's a demonstration of how I imagined the scene: https://drive.google.com/file/d/1JMcc2XcjaS5PL9BZakasmDnymy9ELi3F/view?usp=sharing You can use that as a reference, but don't feel like you have to copy it exactly. Feel free to re-submit while sounding like a young boy/kid.
