Well here is the outside, done but missing some extra decorations, i made the tower 4 times larger, plus the the obsidian mountains surrounding the tower adds up to about 12million blocks so far. the goal is to get to the top of the tower by finding a button (key) to an iron door which then opens the portal to the next level. there are ten levels in total each with their own distinct enviorment. when this is done i estimate it will have over 16million blocks plus the End world which will be basically heaven with a massive mansion and tons of other col features.
