For this drawing, I drew a scene from Reading town centre. I picked a building that I could observe corner on. I used biro on thick cartridge paper and I worked a4 size. I tried to use every possible vertical or horizontal reference to ensure that receding lines were drawn at the correct angles. I tried to use the vertical corner of the building as the reference. 

Below is my drawing: 

When I finished my drawing I stuck together 4 pieces of a4 tracing paper and placed it on top of my drawing. I then drew all the parallel lines and tried to get them to meet their vanishing points.

I found using a ruler to check the angles and receding lines very effective in helping my perspective and accuracy of my drawings, this I see definitely a technique I intend to use going forward on all of my drawings.
