What a very cool and sketchy style! I like the creepiness factor it gives the last character, too. I think even though your sketches aren’t perfect, you did a pretty good job on the proportions of each character.
My first fanfic was about the Rainbow Factory and while it was more about meeting a word count than making something amazing, I still wish it was a little better. I’ve edited it way too many times now so I’m just gonna let it be since I have other things I’d rather be writing on.
