And third time's the charm, I also think it looks like Venus is floating. I think it's partly because of the shadow beneath her, the way it's positioned seems to suggest that she's not directly sitting and instead floating. Also maybe because her butt is positioned a little high up or something maybe (wat). :V
Venus will never stop being so damn adorable, and the details in Flo's face awe amazing. I have to agree with Star though, it SORTA looks like she's kinda floating, though it could just be a POV thing.
