Overlaying Photographs, Sketches and Tracings

I've overlaid my tracings (see previous post) to make this great crowd of partying glasses! As the sketchbook closes they raise up giving a 3D effect, it's difficult to photograph but you may get the idea in the picture below.

I also overlaid the utensil holder sketches. I like the sort of misty look you get with the layers of tracing paper.
