Well, to be honest, I'm actually used to drawing costumes for Asteria's characters. His oc's design is a bit similar to the fan art of Kalim from Twisted Wonderland that I drew 6 years ago.
I designed the Overblot (basically, dark version) of Kalim. I didn't know about him in 2020, so I was a little surprised when I found out about him.
The fan art I drew six years ago was originally based on Jasmine's costume from Aladdin. So, it was a really interesting experience with one coincidence after another.
