DTD, Welcome. Its very nice to see pictures! Forgive me but when you said you have your own backhoe and tractor my thoughts went straight to:
1) I would make it bigger
2) I would make it at least 12 ft deep (fish need deeper water where it gets cold too)
3) It looks like you have lots of stumps to put back in when your done.
4) As soon as im done digging im tossin in lots of FHM/Gambusa minows in to start the forage base.
Now that im finished dreaming about your pond, whats your dream/intention? Just to keep the bug populations down or do you want to fish for certain types of fish turned to nuggets dipped in_________(add your favorite dipping sauce)? Give us the full monty. Whats gonna happen with this pond 5 yrs down the road? Have you planned that far or even thought about it?
