The drawings you can see on the picture are drawn by my nephew except the first one of the second row (its mine; I’ve shown him as reference). He is 5 years old and just learned how to add numbers. He was talking lot during drawing. On the second tree he put three different colors and he was explaining me why he put those colors. He told me he doesn’t like to put only green colors, its boring. Then he put colors on the next two trees and he almost avoid the green color. I thought about myself. I am sure, I am yet not that much smart…
