Yeah, I studied the clounds for awhile and I definitely can see.
1.Bowser's face
2.Ridley's face, it's right of bowsers face and the way I see it it's looking straight forward
3.Hand Holding a Smash Orb
4.Batman or Black shadow, although it overlaps were what looks like it could be wolf/falco, it's to the left of the hand
I think it's just WAY to much of a coincidence to have all those shapes there that there MUST at least be a few of those that are correct of that I am sure, It makes since to since all of those are pretty likely, the face that I think is black shadow could also be a different horned face although I'm not sure whom, and I don't necessarily think the Wolf figure is intentional as the batman face overlaps it, And I also see a face that looks like dracula or gannondorf to the right of the hand but left of bowser.... I think if they were just clouds there wouldn't be that much stuff in them.
