Thank you, metouto, but #87 is not from me ^^ It's from one of my two favorite Minecraft builders, Jamziboy. The other one is Madness64, who is the initiator of the Kargeth City Project. Both gave me good ideas and instructions on how to build nice and good looking things... If you want to see some real epic builds, have a look at Westeroscraft!
Here's an awesome view I came across looking for a good spot to make a video. Note that the open space to the right a bit is not unloaded world, just a huge overhang. You can actually see a little sunlit terrain beyond it on the left edge
