The hunt for a decent picture for my cards

I want to send some holiday cards out (VERY SOON!) and as in years past I'd like to include a photo of the kids. Only catch - they are not feeling very camera friendly at the moment. This one could have been halfway decent if only dh hadn't decided to chop of the bottom half of their bodies. It's unbalanced looking the way it is, and I can't crop it any further because their heights are so different. Back to the drawing board methinks... (and this time I'll do it myself!)
