So I have not really made anything too impressive on the server (without help)... So i'll share some of my single player screen shots. (idk if this is just for server builds... or builds in general) But I'm sharing any way.
So first here is something extremely random and unfinished. Its a front entrance to a future castle that I will probably never find the time to finish.
--------------------------------------------
Now onto a castle build that took me a VERY long time... Yes I used MCedit for the terrain... But everything else was placed by "hand".
-----------
Here is the base and the bridge. This took me around 2-3 hours... The bridge goes on for quite a bit out of the shot. There is also a rail system under the bridge. *before I released the water...

Now here are some shots of the finished castle. I forgot to take screenies mid project

sorry.

I just made up this build as I went. Its nothing too impressive. But it did take me quite a while, and I like how its on a overhang on a waterfall. Hope you enjoyed looking at some of my work. Feedback is encouraged!
