Here are two simple ways to say the same thing so an 8-year-old can understand:
- Option 1: "Thank you for the beautiful drawings! We looked at them carefully and have a few small notes about the details. Please remember them."
- Option 2: "Thanks for the lovely drawings! We checked them closely and have a couple of little suggestions about the picture details. Please write them down."
Pick the one you like best, or mix words from both to make your own version.
