Ehm, you two were discussing the original inspiration for Druuna, so... no you are not

:-D, since if you look at the interview, Serpieri was very specific and explicit about the original inspiration, independently from how then over time her look changed/adapted.
Don't be a Parisian

:-D, or as they would say in Lyon, a "capitaliste"

:-D (hi hi hi, this is an evil Frenchy joke, done in English).
Though the original inspiration is not suprising, don't forget Serpieri is Italian, is not exactly a little boy, and the Italian beauty reference for a long period was the kind of Silvana Mangano (he is old enough to use that), then Sofia Loren.
Not exactly the skinny type, Myriam would be in good company ;-), if you look at these pictures courtesy of the web (and think in her picture of a beauty pageant, Sofia Loren was only 15, she grew still some more after, "growing" ;-)) - so, not surprising the first inspiration was a very curvy (but nasty me suspect the fact was also very naked, and coming out of water in a kind of 007 scene, helped fix her in memory ;-)) Italian woman.
About the reference to Valérie Kaprisky, also not surprising, she was considered a sex symbol in Italy (though at least as far as I remember she could also act), and Zorlun, French women were for a long time considered more "liberal" (or less hypocrite, points of view) than Italian women in Italy - though that "liberal" must be considered in a positive way - so, not strange either her sensuality could have inspired him.
What is true, is that in some strips he has given her a bit of darker complexion, and has pute her in a variety of contexts, but is the same as Myriam, you cannot be too precise on a fantasy thing (and don't forget he is drawing her, not using a fixed DAZ asset, and even you yourself changed a bit Myriam and Kathrine over time), and you cannot use "native" as a precise etnographic indication.
He is an Italian artist, not an etnographer, the refences to brazilian, to "native" in your French text, all point just to the same thing (though requires knowing enough the culture of the country) - fixed images that could be called stereotypes, but in this case I am sure in his mind are considered positive, about women from certain part of the World - again, it is not a scientific paper, cannot be analysed with Cartesian approach, just appreciated (or not) and liked (or not) as it is.
Though I admit I am very surprised to see how diffused and popular was in many countries, I knew Druuna, but to me it always was a very Italian thing, exaclty also starting from the look.
