Here's a cathedral I made a good while ago, Nothing much too it except the fine detail. I only spent about 5 hours on this, and it wasn't meant to be a good build.
It's on a 384^3 map, and the build would not fit in a regular minecraft world. That's how almost all my builds are, they're that big lol

Comment and diamond if you think it's good!
(Updated for the renders, I decided to try this time!, Leave a comment on how you think it looks)

For those of you that want to try to convert it, I added a download link.
Rename the file to 256_256_256.mine and import it with mcedit. Should be good to go then lol
