Clash of Clans Level 3

 

Hey people!  I got the lab upgraded to level 3, same as the barbarians.  I got attacked by a level 2 Barbarian King.  I put walls around the base and I am trying to put a second row of walls around the base.  You can see my barbarians.  Has anyone defeated the barbarian King or even an Archer Queen?

I am trying to upgrade my goldmines, one to level 7 and another one to level 4.
