The physical appearance is great, but too close to reality when trying to communicate the design. It would help to get the idea across if the user could select the colors and the transparency shown in component color cycling mode. Right now I have a design where one component is covering crucial aspects of a design. I don't have a good way to show how the components under this part interact with it. If I could, I would have hidden irrelevant components, made a couple components light gray, added bright colors to the components under discussion and made the covering component somewhat transparent.
