i like it...also this is one condition where dust on sensor works and adds to the picture? (pinhole is extremely small aperture-i don't know what yours would be equiv in f-value but with extreme depth of field i think we are even seeing the tiny spots on sensor which under normal lens conditions wouldn't be possible) i think this is the reason of the small black spots...but i may be wrong of course
p.s. very easy to figure out the aperture: another shot of the scene with a regular lens would give you the basis of comparison: i would think yours is extremely tiny: 1600 ASA 1/30 sec for cloudy sky in daylight...f/256? pps. pinhole may be used as a good dust on sensor check for the anally retentive.
I do think the dust and high ISO noise add to the picture, like scratches on old Super 8 film. :)
It is also good to see how well the sensor cleaning function actually works since it does manage to get rid of dust quite well but due to the nature of the pinhole there is dust back on the sensor quite fast. These dust spots would not be visible at any aperture on a normal lens since they don't go below f22.
I am not sure what f number my pinhole lens has but might be worth finding out.

Thanks for your comment!
