Yes, these are two girls that seem to be off the radar.
When I like think watch VGHD girls, I tend to give them a real life caracterisation.
So for existence a girl could be the sexy neighbour (e.g Manon), my firends big sister (Bijou), girl in a disco (Melissa), shy sexy innocent girl (Morgane), fun loving stranger (Dorothy Banks).
The great models like Alizee can fall into several characterisations, while a few like Chems stand out without having any characterisation just simply because their general performances and presentation is exceptional (to me at least).
In other words, most my favourite models represent some sort of real life fantasy.
The problem with Bernadette is that (for me) she does not really fall into any real life characterisation. She is pretty and sexy, but she does not represent anything other than being a VGHD girl.
On the other hand, I imagine Nicca as the kind of cool attractive girl you see round Univerity or college, but who i perceive I ave no chance with.
So on that basis, Nicca is for me because she represents a reali life fantasy, while Bernadette just seems like a decent, but not great, virtuagirl.
That is just my opinion.
