Thanks for the comments thus far
I originally posted this in the "people" section and I was wondering what happened to it.....I guess a mod. decided it fit better here. Anyways, I was a bit vague when I said "on-board flash". By onboard flash, I meant my 580 with the camera, not the pop-up.

Was your flash perhaps pointed up a bit? Looks like there's a bit of light falloff at the bottom.
The flash was mounted on a bracket above the camera and due to the fact that I was so close to them when this pic was taken, it did have some fall off towards the bottom. Plus, the angle of her dress in the lower left corner also creates the effect of more light fall off or vignetting. I could've tried to "fix" it in PS but I actually thought the effect worked well here.
