This is a really nicely conceived and executed image; it is spot on for the challenge, and the use of the white background serves well to draw focus to the suitcases and Waldo. That said, it doesn't really speak to me, but this is a personal reaction rather than a reflection on the technical merit or the art of the shot.
Unique take on the challenge, I really like the concept though I am not too sure how much favour it will find with others, for some reason on my monitor the skin tones seem a little blown out
Well, I guess the person is "hidden"; you've just taken a different slant on the Challenge. The photos that will do well will be the ones where the person is harder to find than this. Good shot, otherwise.
