Here are the results:
1st Standard Pinhole for baseline.

3rd Subject at Infinity with Epoxy Lens

As you can see there is a fair amount of softness. There are probably a bit to many variables to really say whats causing it, the stability of the box, the edges of the pinhole, the size and curvature of the epoxy bubble, the light transmission properties of the epoxy, and user induced movement when opening can closing the lens cover. All I can say for sure is that the epoxy lens makes a smaller image circle within a similarly sized box than a standard pinhole.

I think it was a interesting experiment, and future experimentation should be looked at though different materials such a other brands of clear epoxy or superglue.
