Doesn't seem long ago you made it to the Gunpowder Age. You do move quickly! I'm still part way through Gunpowder Age (level 89). Looks a good layout, although I think I'd place the traps in the inside of the left container, with the caltrops just behind the door, followed by a spike trap and lastly the ambush trap. That should also take care of potential Guerrilla units sneaking in too. I suppose ideally it would be better to have the Acropolis in the middle with the garrisons and stables spread about a bit more but I see you're trying to protect the town centre. Perhaps at least move a garrison over to the left container, swapping over one of the towers.
