Smile new sub-panel installed

I have a private camp site pole 50' from a transformer with an outside 100amp siemens double pole main lug breaker box installed, using a 100 amp double pole backfeed breaker as a main, feeding two outside gfi 20 amp circuits for occasional campsite usuage, properly grounded with two 8' ground rods. This has been inspected and passed.

From the above, I ran a 2-2-4-6 aluminum direct burial cable from a 100 amp breaker, into an 18" trench, using 11/4 pvc conduit into and out of the trench into a shed/workshop 100 amp siemens main breaker box. Both the neutral & ground were connected to the ground buss bar in the supply box. In the sub-panel box, the ground was connected to the bonded ground buss lug and the neutral connected to a lug installed on the un-bonded neutral buss bar. A #6 copper ground wire was also connected to the ground bar and grounded outside onto an 8' copper clad ground bar. Do you good folks see anything wrong with this installation? Many Thanks!

Sounds good so far.

The shed subpanel should have a main breaker (or backfed "main" breaker) to serve as a building disconnect if the panel has more than 6 breakers total. Some inspectors require a main if the panel can take more than 6 breakers, even if fewer are actually installed.
