Not bad. But your credits and alloy are open in the corners. I would attack it right behind the transports and in front of the factories. Try to bomb the oppressor out and trip the sonics then dump lots of troops to ripe the credit and alloy before they reset. If your SC is loaded it will also trip on the victim troop on the sonics and I might be able to get them down to the bottom for heavies and more bombing. Lots to pull off for a successful attack on the resources tho. So that's a plus. A hi level Kessen shot could take out oppressor and SC but that's a tough shot even for the better reb squads. Just some thoughts.
One suggestion might be to add traps near the creds and alloy. I have a L10 imp base too. I've gone to a hi corner base lay out with double wall in the back for the HDs. Makes it very easy to 3 star every HD and grab the frags.
