I thought there would be a lot of selective desaturation in this challenge, but didn't expect one that would use it so subtly or creatively. Just the tiniest splash of color, hidden behind shades of gray. I generally like the image, with an interesting perspective and good choices for the lines (running front right to rear right and rear left). Composition is good, though the brightness in the back headstones is a bit distracting to my eyes (though perhaps you were using that to draw attention away from Waldo?). Well done.
I like your perspective here. highlights are a bit blown, but I think you may have done that on purpose. I wish Waldo were doing something a little more meaningful which would add to the theme of your photo.
Well the desat was a very nice clue to help find Waldo...Lovely shot. I love the diagonal V shape of the headstones which really creates strong leading lines especially given the the headstones on the right run up along the run of thirds line. Personally whilst I can understand why you did it in terms of the challenge I think I would have preferred it without the desat which distracts a touch (imo) from a wonderful image
