Content progress development:Design issues and treatment: Ideation and sketches

Based on my target audience - 8 to 12 years old kids, I did my designs in the style of kids paintings. I made them colorful and I add some animation and games in my application. So that kids won't be too boring to use this application.

Design 1
This is a common design. Because my topic is about Chinese traditional style architecture, I add some Chinese elements in this design. I draw the objects in Chinese style.

This idea came from one of my precedent studies. I use an earth as the main object in this application. Kids can use the arrows to turn this earth and view each part.

In this design, I want to make it like a chess game because kids sometimes play several chess games. I will make a map for the chess game and a dice. Kids can use the dice to choose the steps they want to go to view each part.
