architecture drawing-class exersice-prespective drawing

perspective drawing is a very good to show the space and 3 D of one building, it gives audiences a idea or a atmosphere or the depth of the building, it is different from the parallel projection, it looks more real then that, as perspective drawing follow the rules of things close to you is big and things far away from you looks smaller, though this exercise, I have learned how to use a photo to assist you to draw a perspective drawing, it is very useful, thanks tutors
