Hey there! I am currently building Dr. Wily's castle from Mega Man 7 in Minecraft on a multiplayer survival server.
Here you can see what it looks like from the original game and my progress on it as of now:

Right now it's just hovering on top of a dirt platform. I want to terraform and make a hill around it after it's done because
then I know for sure how much space is going to be needed.
I do try to imitate the original image as much as I can but I have been and will use some creative liberty for some things
that end up looking bad in MC. Also, I can make the interior and sides and backside exterior of the building entirely as I want.

You can follow the progress at www.twitch.tv/spiriax where I have building streams making this thing.
Stream time varies but it's usually around late noon to late evening/night for central Europe time.

After I am done with this build I want to build more on stream. Here you can see some of my older projects (most being many years old): imgur.com/a/lcDV2Eh
