Hi Hive account@macoolette, and thank you for your interest :)

It's funny because just yesterday I was making order in my recent drawings and I noticed my inclination to draw pairs and couples. I may have to go back in my drawing history, but I think it is quite a recent thing.
Under the stairs I wanted to add a touch of mystery and a second narrative: another two people on a white boat, one of them holding a torch to grasp the view of a tunnel.
The violet thing under the stairs was meant to be water, so their having a tour on the undergrounds by Vltava river, I guess.

I like the fairies guardians version better, tho! Hugs!
