Maybe watch the Lego Star Wars Holiday Special, I know it’s a silly recommendation, but you might get some ideas from there, but I still don’t get how that fits theme ‘Best Wishes’, sure, it’s Christmas, but that’s not necessarily a best wish, Is it?
I got an idea for a scene: An intergalactic delivery package guy, outside his ship, looking into the sky, seeing all those planets, holding a gift, thinking about his kids, hoping them the best Christmas, wishing he was there with them. Cheesy, I know, but fits both the sci-fi and the collab theme, if you don’t want to create the character model, you can simply cast a shadow, and have the sci-fi looking gift on the floor, near it.
