This has been a work in progress for quite some time. I've only really played one Minecraft world, on and off, for nearly a year now. This is the product of all those efforts. It's mainly a series of individual buildings/areas connected through a series of sky bridges with a powered rail-driven train system between them. There's also a bit of explored area in the Nether with a portal to a bit further off where I designed some castle ruins for flavouring.
