I'm guessing the traps in corners are because you don't want to pay rearm costs right.
Honestly for a farming base its not that bad, only thing I would change is put your TH way in the corner so people can snipe it easier, buy a white flag and some flowers and decorate your TH with it to show its not trapped. you want people to snipe, give you a shield and leave you alone. if you put your TH near your base and the archer I spawn to snipe it gets killed, I will raid your storages just to prove a point.
