To determine if your story's animation is appropriate, you need to consider how well it conveys the intended emotions and messages. Also, look at whether the animation style fits the story's theme and if it engages the viewers effectively.
I'm not sure. It could be a professional animation studio or an independent animator. You might need to look for credits or other information related to the story to find out.
It really varies. If your story is full of adventure, has educational value, and avoids scary or mature elements, chances are it could be animated for 9-year-olds.
In my 'my animation story', the most memorable part was creating the world where the story took place. I designed every little detail, from the mountains in the background to the tiny flowers on the ground. It was like building a whole new universe, and when I saw all the elements come together, it was truly amazing. There were different climates and terrains, and I had to think about how the characters would interact with their environment. It took a lot of time and effort, but it was well worth it in the end.
Well, without knowing the specific details of 'my first animation story', it could be a very personal and exciting experience. Maybe it was about a little character's adventure in a magical world, full of colorful sceneries and friendly creatures.
