Hi Brian, pretty cool though I'd suggest you add a little chaos (yes, a Bill Fleming term) - the match sticks look too regular - nudge them around a bit to make the image feel more natural...

Though granted, if this is just a modeling exercise, you need not bother ;-)

PS - Other suggestions from his Photorealism Toolkit book would be to add some thickness to the cardboard (offset-shell) and to fillet the match sticks so the rounded corners catch the light more realistically during renders.
