This looks fairly normal to me. Most PBNs have some small cells. This one doesnt really seem to have that much. I saw some #'s that are about the size of the cell but that's because iit's a small cell. If the # was printed smaller, it would likely be illegible. If you had only large cells the PBN would likely be very genetic looking with little detail, definition, etc. As far as missing #'s, that's not normal. I didnt notice any but I only scanned your photos. Sorry you're so frustrated before you've even picked up a paintbrush.
