Yes, I can make non-lewd pictures and in my other hobby I do frequently and often.

Also yes I should be making actual profile art of the main characters of my little universe, but it is far more important that I draw this one little critter from one episode of the 30 chapter story that I haven't written yet.

Anyhoo, here's a willowisp, or my newest take on one at least.

They get jars when they're young, and spend their lives filling them with little bits of lights that interest them. Rainbows, reflections, streetlamps, neon signs; you name it. Every wisp's jar is unique.
They used to all be bespoke blown glass baubles, but nowadays glass is so commonplace that many younger wisps will take a cool looking container from the human plane. Old-style coke bottles and mason jars are a popular choice; convenient too.

They don't technically fly, so much as hang off of little clumps of light and swing around; this gives them the bobbing light motion that will-o-the-wisps are known for.

They travel around in family groups, occasionally merging for social occasions. Ironically, these days young wisps often get themselves lost in urban areas at night, getting disorientated by nightclubs and streetlights.
