This is an easy one.
Multiple grounded conductors under one terminal are no longer permitted. With all the unused terminals on the bar, this is easy to fix.
This is a subpanel, therefore, grounding conductors cannot be mixed with grounded conductors. This is also easy to fix, simply install a ground bar and remove the grounds from the neutral bar.
Otherwise, this "installation" is very neat.
Sorry, I can't cite code references since I don't have the '02 book. I'm sure other members can.
