My process for the Bad challenge went something like this: "Oh, that's right... it's Tuesday! The deadline is an hour away and I haven't even thought about it. Hmm... well, I just finished taking photos of opening day at the local carnival, so I'll shoehorn a terrified expression in there and hope for the best."
I love it. Not sure I would crop the third kid out, to me it adds a lot to the shot. The older kid still appears apprehensive, middle kid looks scared and the little one just looks terrified. To me all three help make the shot a great image.
