I would like to ask, photography generally wants to shoot people higher, usually squatting to shoot you up, so should I look at the camera or look straight ahead?

Looking up a little, people look tall and powerful. If you look directly at it, the effect will be reduced. In addition, pay attention to the choice of background. Try not to choose objects taller than people. If tall objects are inevitable, try to keep the characters away from the background, or blur the background through the lens to achieve the purpose of highlighting the characters.
