These vectors constitute the July 2021 monthly reward for Starponys; like ./skysparkle and ./endearment we went through version ping-pong where I didn't understand some details, WIPs got returned with crudely drawn circles and he paid extra to appease me and ask for more versions – including one with Trixie's twintails.
For rewards like this every month check out my Pixiv Fanbox.
