It took about three days to build the first one by myself. The larger dome took only a day with 3 others helping. The white building covered in redstone torches is a strip club. XD
I love that guy who does the "AWWWWWWWWWWWWWWWWWWWW!!!!!!!!". Lol. HOLY FUCK THAT'S MIGHTY IMPRESSIVE!
That's Simon, he does most of the voices for the characters as well. Tbh, he does get annoying after a while.
I haven't built anything too grand, my friend who is running our server keeps changing it to test out mods, but the world we play the most in, I have two structures I'm proud of. One is a large castle I'm still working on, the other is a pirate ship. Its not very large, but I threw it together in about two hours, it has a captain's quarters, a treasure room and you can climb to the crow's nest.
