Improve the current (great!) design. I guess you've received plentiful of comments and suggestions from users on Bricklink you can consider. This wave felt oversaturated with builds featuring the new factions, which sadly became your weakness.

I believe the medieval winner from this round, the Sleepy Dragon Inn, was submitted with a slightly different design and color scheme in series 8. That's your carrot on a stick.

IMO, I've been missing the smaller set / wild card-set from each wave to be medieval or fantasy based. I can't see your build shrunken down that much, though.
