What is the ruling on placing wallpaper with motivational children's drawings or cartoon animal images in children's rooms to bring joy and encourage studying?

If the drawings and pictures of animate beings are complete, and nothing is missing that would cause life to cease if it were removed — such as the head or chest — then it is not permissible to display them. If they are displayed, it is obligatory to efface the head, or something else whose removal would cause life to cease. They do not take the ruling of dolls played with by children.
