What are the characteristics of Americans and British?

You can’t tell from the appearance, they look too similar. But their temperaments can be seen to be different. The British are relatively reserved and conservative at first glance. The Americans are more open and friendly. Temperament is difficult to express in children's drawings, so I suggest you use clothing to highlight their differences. Britain People dress more formally, with a top hat and a cane (gentleman image). Are they Americans...you can draw the Stars and Stripes pattern on their clothes.
