What Should I Change?

This new base design I created isn't doing very well atm. It keeps getting wrecked by the barb-archer strategy. What should I change in order to make this base better? The empty space in the bottom middle is where the barb king is going to go (I'm at 6k DE.)

Stagger the T-junctions, protect your air defences more, plus segment your core. Healer-giant would totally wreck that base, and also a single breach to the core will leave your important buildings all exposed.
