This should be your first basic drawing - note the right wall vanishes to the left, and the left wall vanishes to the right. the only consistant thing is vertical lines.
Next do another more complicated clay with some doors, windows, lights or more reallistic features. You should use newsprint on the edges to place the vanishing points.
Using an actual source find the vanishing points. Then do a drawing from 'life.' Either from a photo or from observation. Use your phone camera if you have one to check what you are drawing.
Your final pespective blog will have three drawings on it.
