Mark, if you extend all the "straight" lines of your building up in to the sky, they will eventually converge at some single point. That's the vanishing point.

Now, IMO this is a subjective thing. I shoot a lot of wide angle, and I especially like the way it distorts building lines. In many instances, I try to exaggerate this effect.

Still, from an architectural photo purist's point of view, this is generally a no-no (especially if it's off by just a bit). And even though 3-point perspective does indeed have a legitimate third vanishing point at the top, in photographs you usually want the vertical lines of the structure to be parallel.

Photoshop's transform tool would allow you to easily pull the top corners of the frame out a bit to straighten all your vertical elements.

BTW, saw this shot on your site. Looks good in B&W, too...
