Your ambient occulusion pass is wrong. How are you doing it? It looks like a environment override something?

You need to use Render Elements Vray_ExtraTex with vray dirt as the map, adjusting the dirt parameters to suit your scene.

Then use multiply in post and adjust opacity to suit.

Also, you shouldnt be getting flickering in that scene. Seeing as though you are compositing anyway why dont you do the people seperately using vray matte object?
