Haha, I love people's suggestions. Adding the princess maybe detracts from the isolation theme slightly- but I do like how it adds to the humor and adds to the idea that isolation doesn't have to last forever and that there's hope on the horizon,
The princess bringing supplies is also hilarious and would make this feel like a covid-19 commentary with the timing- it would make the interpretation more specific.
The princess climbing the beard is also fun, but would add some unpredictability as far as the contest theme and judging goes, since it detracts from "isolation. It could work well in a portfolio though.
I think pushing the perspective is a good idea in any case. One possible idea that may or may not work would be putting the background princess on a hill. It could indicate it's not a strait path on ground level to the tower and may give more interpretation to the tower possibly being higher up, if they are in an environment with hills and valleys. Does that make sense?
