That is some interesting shrubbery. I'm sure he's there but I can't find Waldo. He's probably somewhere in the trellaced garden area (called an arbor?).
OK I fess up you have got me beat, though I feel sure at the end of the challenge when I see where waldo is hdden I will slap my hand on my forehead and go 'd'oh of course, how could I miss it'
In terms of the image itself, very good and the way you have framed the shot really works well, as does the B&W conversion
There could easily be someone hidden in any number of places but I don't see anyone. Think I would probably like this better in color as those big mounded bushes look very odd to me in B&W.
There are some interesting elements to this image, and some interesting compositional choices made. I generally like the tones, though the blacks aren't quite black, and the whites aren't quite white. I think the image might reach me more if there was a touch more contrast, and if the middle section wasn't so busy (between the trees and the pergola beams). Waldo is there, but I think the distance this was shot at to hide him makes it harder for me to appreciate.
