Personally, I ship Huntlow, and I think that the main reason that Goldric exists is because Hunter and Ed are the same age (because they've barely ever interacted in the show).
But I think it's an okay ship!
I could definitely see them having a cute dynamic.
So, if they got to know each other better, and if Edric would actually be able to understand Hunter and everything he's been through, and if Huntlow didn't exist, I might ship it. :)
Either way, though, I love that fanart! It's adorable!!
