Wow, incredible. I give it a standing ovation. This is seriously polished, and has such a cool aesthetic to it. I'm dying to know how you made the background.
Hi! The backgrounds were made in CLIP STUDIO PAINT by using a white pen over a black background, the edges were done with various gauze and crosshatching brushes in the same colors. The same thing can definitely be done in free softwares like KRITA though!
