The fanpoppers who are most similar to the Winx girls are

Iti (nmdis). Her hair is most likely like Layla/Aisha but she mainly looks like Flora. Completely similar. Not to mention, both of them have the same personality ;P

Thanks @Farhah.

Well I think Mel is like Stella...she almost resembles her. And that's not because she is blondie (I know i's the point) but her face cut and lips are indeed like her.

Oh I have to agree with that. Mel and Stel look almost exactly the same :)

I think Farhah is a mix of Flora and Layla with a touch of Musa

I think maja looks like bloom
Iti like flora
Mel like stella
Meeka like Aisha
