Space Castle Mash-up

When I first saw the Nexo Knights theme, I was excited, because I figured people would jump on the whole medieval sci-fi genre. There haven't been many Nexo Knights MOCs yet, but this one by Dubbadgrim is exactly what I was hoping for. It combines castle elements, like the main wall and the landscaping on the base, with some cool science fiction parts, like the anti-aircraft gun and the robots. I wish we'd see mash-ups like this more often.
