The first picture may not look pretty, but pretty is not a code requirement.
Pictures can be deceiving, so it is not easy to tell if the 40% fill has been exceeded…it may have been, I think it is a close call the way it looks to be filled, but a calculation would have to be performed.
Yes, a couple of the cables do not have the required measurement of sheathing, and the PVC fitting is missing a bushing, but this install looks like it may come pretty close to being compliant. The splices are close to being 75%, but how can one tell from the photo?
I would say the contractor may be able to slip a little more sheathing into the panel enclosure, that would leave only the bushing as an issue.
Remember, we do not inspect for personal taste, but minimum code compliance.
