This is great Julia, Waldo popped into my mind too for this challenge. This is really well-executed. I love the teeny Waldos popping up on the first slide and I never thought I would see Waldo face down in handcuffs :)
For me there is one small problem with this: When I found him, I wanted to click exactly on Waldo (I am a bit OCD!), but because (I assume) you are using hotspots that show layers on mouse hover, when I move my mouse on Waldo, the layer changes, so I had to click in the vicinity of Waldo to get to the end. I am not sure there is any way to really solve this entirely (at least not without rethinking the whole interaction), but you could possibly improve that aspect by having Waldo appear in an area of the mag glass where you can click without it changing to another layer, for instance in the middle, if that makes sense.
I'm being super picky though, I think this is really great!
