An image I posted was not approved, or it was and got deleted or something, but it said it contained Human Only, which I don't understand considering it was Goombella and Lady Bow, but more anthroized/humanized, and there are plenty of other artworks like that, specifically of Goombella behind humanized and solo or with other humanized characters

Also, sorry if I shouldn't be posting something like this here or at all, never really had something like this happen

Skin color doesn't count as a significant enough difference to move from human to humanoid for approval.

If it looks like a human/humanoid and does not contain any features that would otherwise make it "furry", then it would be deleted (see humans and e621 for more detail).
The character's actual species or lore does not matter in this case, nor does any already approved posts that feature said character.
