Your base is destroyed ~40% at the moment so it's a bit hard to tell, would be better if you could upload it, as someone previously stated.
But I took a glance, and don't believe I saw teslas. I'd build those, since TH8 gets 3. Expensive, yes, at 1mil per, but it's another tower you'll have protecting you. I personally wouldn't really go for air defense as an absolute priority, actually. At 1400 three level 3 (did you have 3? Can't remember now) should suffice for anything thrown at you. And if it's 5+ dragons, then whatever, chances are they probably didn't make a profit anyway.
And, to be honest, the only reason you'd have to upgrade walls is for the looks.. still takes two lv4 WBs to take out lv6 walls. Not sure about 5 and I doubt you'll get attacked by 6. It's still a good thing to work on them though.
Also lol @ the lack of crit from the last few posters even though you clearly stated you're aware of your wall situation
