The Nintendo US SNES Classic page shows a bit of official artwork, but the Nintendo UK SNES Classic page shows even more. We have our first officially released artwork for Miyu and Fay (to my knowledge). With the official release of Star Fox 2, Miyu and Fay are now technically canon characters, to say nothing of story points in the finished game no-one has yet seen. It's going to be an interesting year for Star Fox lore.
I really like this comic-like drawn style of the Star Fox characters. Now, who wants to volunteer to do Krystal in this style?
As a side note, it looks like Nintendo of Japan has not yet announced that the SNES Classic will be released in their region. Curious.
