Any advice for my base please... TH6

I know my base is not quite good, but how can I improve it?(except walls, I will upgrade)
(I'll place traps later)

Thanks

P.S. Is it better to upgrade Cannon&Archer tower first or Barracks&Army camp(current troop 120) first?

army camps are just as important as the def. stuff. You need the troops for farming.
You can use one builder for army camps and two for the def.
PS: I will upgrade the mortals first, but that's my opinion.
