It's not uncommon for a change in link graphs to cause a temporary change in rankings. Be patient, each page is viewed on it's own merit and it takes time for any link changes to propagate to all pages.

If you're doing what you should be doing, ie: creating solid content and letting interested people/webmasters know about it, don't fret a temporary drop. It takes time for all pages to adjust, especially on larger sites.
