They're both floating ruins in the skywheeeI like how you put Blaze and Jet together - even though Blaze's Sky Babylon from Sonic Rush is not officially confirmed to be the same location as Babylon Garden from the Sonic Riders games, I can definitely see the similarities when I think about it. It's stuff like this that makes me love your work; you look at the small but interesting similarities in the Sonic franchise and draw thoughtful fan art of that
