We started out with a big piece of paper and then made a box and a vanishing point.
For the project we could only use vertical and horizontal lines. First I made the box in the middle of my paper was the back wall or the wall you started from. The the made the ceiling tiles. Then started ti make the window. Finally you put everything in the room. Drawling the objects was hard but the ceiling tiles was not that hard to drawl.

Kristen Bezhani has done a very good job with this project. What was successful in her project was that the window really looked like the window in the actual room. She got the point of 3D effect.
