Takes a few hours to build, here's what you'll need to make it:

White wool: 209
Orange Wool: 201
Light Blue Wool: 162
Pink Wool: 533
Light Grey Wool: 4
Cyan Wool: 160
Purple Wool: 176
Blue Wool: 82
Brown Wool: 85
Red Wool: 682
Black Wool: 836

Over all that is 3130 pieces of wool.

I recommend using creative mode or using the schematic if you want to add this to your world.
