What's Wrong with this Diagram?

This took longer than I thought it would. I kept wondering why we were upsizing one of the sets of feeders to 125 amps, and I couldn't understand.
 
Sorry, I didn't finish my thought. NEC 250.24(A) requires the grounding electrode conductor to be connected to the grounded service conductor at the service, not in a sub-panel.
