They asked me for an LDD file, because most of the entries were done virtually, but I did not have one, so they figured it our on their own. 🙂 There is also a video that the contest winner posted of his own build in the game: https://www.youtube.com/watch?v=zGkq73rDW0U
incidentally, my copy of LEGO Worlds is supposed to be delivered by DHL tomorrow. Of course, I don’t have a PS4 to play it on and even if I did the winter worlds is a apparently a seasonal thing that ended January 2nd. 😀
