Those are pretty good shots: pinhole cameras were never amazingly sharp anyway. And yes pinhole apertures are definitely small enough that defraction will be be a non-trivial issue (I think that's a large part of why they're never amazingly sharp -- like cheap plastic lenses one has to call it "artistic" rather than a flaw, or go invent something else!).
BTW the "dust delete data" option in most DSLRs is practially made for that sort of purpose -- in theory you just take a shot against an evenly lit untextured surface and tell the camera to use that as a dust reference. For in camera JPEG it should then be auto applied. (For RAW it is up to the RAW converter to do that.)

Yeah, I know that my camera has that ability. I just need to work out how to make it go, which shouldn't be too difficult, if I decide to persist with this sort of artistic.

Interesting experiment.
