STEP ONE THE DRAWING
The first step is to draw the scene. The key point is to start with eye level and then draw your objects relative to that. What do I mean by this? Well, when drawing with perspective, objects above eye level will appear to move down to it the further away they are. While objects below eye level will appear to come up to it as they move away. Another point about eye level which is important is that it basically tells you approximately how tall people are - hence eye level. You can then make all your other objects, cars, awnings, posts, fences, etc. , relative to that height.
