Do you really and honestly think she is hidden? Yes, she's beautiful, and I wouldn't want to hide her either. But the challenge calls for you to hide her. This is a beautiful photo of a beautiful little girl, just not quite on the mark for the challenge.
This would be an absolute wonderful photo if it weren't so dark. Since I don't know what kind of camera you are using I would guess it is a point and shoot camera. Try using either paintshop or photoshop to brighten it up some. She is a cutie =o)
Very good focus and color. Is your Waldo the little girl? If so, while the background is dizzying and she is behind the bear, I still won't go so far as to say she's "hiding". (If I have missed something here, please feel free to PM me)

I didn't have to look too hard to find the hidden person here! Hiding behind the teddy bear right? The crop is just a little too low as the top part of the subject's head is slightly cut off. She's a cutey though!
I can see what you were going for to fit the challenge but I don't really know if it works. Technically this photo could be imroved, especially by cropping. There is way too much empty space on both the right and the left sides, and the girl is very centered which isn't usually desirable in photography. Also the fact that just the slightest part of her head is cut off is very bothersome. Cute girl, and cute stuffed animal, but the photo needs some work.
