Unity ilustration

I use abstract flat style, people with different races and tribes from all over the world which means we are the same in one UNITY, the picture of the book in the middle is science, two different colors between the right and left means all the time in the world, pictures of buildings and plants on the different side, the countryside and the city, and the sunflower plant above means our goal is to grow together, two hands with different colors hugging the heart which means we complete one another
