Here is my attempt at the 32x32 castle challenge. Technially, the front archway overhangs by 1 stud, and the flags stick out past the baseplate, but otherwise the footprint is still 32x32. I wanted it to have a fair amount of detail for a MOC, but I also wanted to make it similar to the older style Lego castles from the 80's so I still kept it somewhat simple and didn't add a few things, such as landscaping.
I hope you enjoy it, I had fun making it. If you see something you like or have any suggestions for improvement, please let me know.
