Wall seperating me from the darkness

To the left you can see my main home base with a massive lava pillar on the roof serving as a beacon. Down the middle is a wall that will keep the bad guys out. The glass along the edges keep spiders from crawling up will minimizing the hindrance to my visibility. This wall wraps all along my area and there area couple of mob traps that catch baddies on the outside and after killing them drops the loot on the inside.
