How do I improve this pic in photoshop?

[TaffyTim]

Hi all,

I have taken a few portrait shots of some friends children, these were done against a white background that turned out plain grey due to the level of lighting on background.

Is there any effect done in photoshop CS that could give it a little more pop and elegance?

I was thinking of boosting contrast/levels but wondered about a slight halo effect around them to separate them from background a bit.

PS This image will be converted to black n white.

childrens faces blacked out to protect identity

any help with examples most appreciated

You need to post some examples if you would like any help with this.
There's some excellent re-touchers on here so well worth posting something for people to work with.
