hm, ok... first of all, do you realize that the way you've drawn the that room, the nearest desk is like three inches tall? Follow the help lines towards the door to the right (which hasn't been drawn in perspective, for some reason), and you'll see that the height of the desk is only like a tenth of the door.
You can't let the drawing area occupy such a big portion of the entire perspective "field", or things will just look skewed and weird. Start with a horizon, then position the vanishing points really far apart, and just let a small area somewhere in between be where you draw your room.
So instead of:
DRAWING DRAWING DRAWING
X-----------o-------------X
DRAWING DRAWING DRAWING
DRAWING DRAWING
You get:
DRAWING
X-----------o-------------X
DRAWING
The reason for this is that a room isn't infinite, like a cityscape with streets converging in the distance. A room has a rather limited depth of field.
