In perspective drawing I have learnt how to draw smaller when it gets closer to the vanishing point. I also you find the vanishing point at the horizon.
Three things about drawing in perspective are.
1 things need to be drawn smaller to show that they are getting further back.
2 the vanishing point is at the horizon.
3 on mountains the further down it gets the darker it gets.
Here is a picture of my art.
