Main Icons Design of Popular Science Mini APP

Hello, my friends!

This is a new project I recently completed. It is a popular science mini application. This is a set of main icons I designed for this popular science mini application.

Its target users are elementary school students, so in terms of design style and color matching, I try to use it as much as possible so that children like it. For example, the icons are simple in shape but have a certain 3-dimensional effect without losing the details. For the color matching of the icons, I use the colors that children all like, so that the colors can coexist harmoniously and contrast and highlight each other. Of course, in terms of style, I tried 2 versions

Looking forward to your feedback!
