Looks pretty decent. Very difficult to 5 star it. I would attack by circling around the base. Staring from the bottom and go clock wise. By the way, how much did you spend on that max wall?
Well if you scope my current layout via the top players, you'll find my 'economy mode' ; every building touching the road for the gold bonus. I've been enjoying a 5d PT haha
Nice layout. I take it the main aim is to protect medals instead of resources? Because by moving the TC outside (or at least the wonder that acts like a 2nd TC for medals purposes) you could hide a lot more resources.
