Made mine in Krita over a year and a half ago when I first started publishing.

There's also this not-yet-published one for the upcoming season 2, redone in CSP, and was much easier to do, though I'm sure not everyone will like the change once its up.

As you can tell, I'm really into stained-glass looking art.
Also did my own banners and thumbnails(which need to be updated cause of my style change).
