User blog:Cubim4/Unseen Concept Art?

So I was looking on Google Images when I searched "Mixels Backgrounds" and came across this.

I would assume that this is Concept Art but i'm not completely sure. Probably some unseen Mixopolis places but I'm not sure.

I also am not sure if these are real or fake. I would assume they are real, as they seem legit to me. What do you guys think?
