This MOC is called Archery Tournament at Clerendon by Mark of Falworth, the builder. He posted this in his flickr lately in Dec, 2016.
It does not look hard to build one, but the idea of having the live effect is great! I really love how the tournament in place. The contestants were split into red and green team, with the king and some audience cheering around. The fence and gate are cool when it is matched with the ground texture.
