I wish that I saw this contest few weeks ago, so I could have more time to finish my work xD. But anyway, here's what I came with, a white castle like palace, based on pictures of one castle placed in Tarnobrzeg, Poland that had all these gothic elements before it unfortunatelly burned down and was later rebiult but many details were lost. I wish I could add some stairs, a garden and make some interior (unfortunatelly the castle is empty :/ ) to this build. The longest and hardest part about this was to find the ideal place and edit the terrain so the whole building won't fly above the ground. What else can I say, I hope you like it!
If you wish, I could upload the whole world and add a link to download it.
I've used BSL Shaders for my screenshots.
