Yes, it is within proportions of all mini blocks, and yes, I did make and design it my self. It is enormous, and was about 14 pages long. I created it on a word file, so it will be difficult to turn it into a acceptable file for a design, so I might not get into doing that. Some of the things I was looking for in mini were previously not on the site, so I had to make my own mini of it, like the stone slab stairs on top of the tower. This only took me 4 hours to create the templates and to make it. Right now, I am working on a mini castle to fit this in as a turret on it, so I am going to need four of these. Hope you all like this!
