Guys I've seen this in multiple places, especially in Winx Club Amino.
A user named Lizzybear5 took the arts of Ultimix and fantazyme, plus the arts of xXDiamondStarXx 's OC and a few more whose artists I don't know. Plus images of Daphne that are fan art, drawn by users here. I think some were drawn by Bloom2 as well, like the images of Daphne. And they took AshianaAquaris work too
I have proof below
Oops I must've left her off by accident, I'll fix it ^^
Was about to ask that too.
