well if he doesn't want any ties with it then that's the best way to do it. I personally love the show heck my rooms filled wall to wall (and part of the ceiling) with pony stuff i even volunteer at everfree. but not everyone likes the show and/or fandom as much.
What ever you want to do, I support it. I admit, I adore Sleepy, but if you want to put her away, then all I can say is that she had an amazing run. I'm still a fan of your work, no matter what you do. So please, keep on being awesome.
Bueno, desde mi punto de vista Sleepy no la vi desde la primera vez que la vi relacionada 100% con MLP, mas alla de que sea una unicornio propio de esa serie. Ella tiene su encanto propio y creo que si mantenes su escecia, ella puede ser lo que mas te guste
