Here's a "photo" that was "taken" at Finn and PB's wedding.
And something you should know; in my fan-fictions they're the same age when they get married (this would have been around...when they're 26?) Remember, I ship FinnxYoungPB, so she got turned 13, this time she decided to grow up with Finn, instead of change back to 18.
I enjoyed designing their outfits and appearance. I hope you all like!
