Nice sharp shots with great DOF. But, since you have used the optics of the
lens, and the drilled brass sheet is merely providing an aperture that is
MUCH smaller than the smallest f/ stop of the Zuiko, IMO this isn't true
pinhole photography.
As I see it, pinhole photography lets none of the photons come through glass
on their way to the film.
Interesting technique, but not classic pinhole.
