People have mentioned how she usually has the same expression and doesn't smile. It's because her teeth aren't that great looking. At least that's what I think the reason is, having seen her smile on video for a moment... They're not freaky, but I recall them being kind of pointy. Or maybe it was just her canines. I feel kind bad for her, because I don't smile much for the same reason. My teeth aren't great and I'm self-conscious about them. But when you don't smile much for whatever reason, people tend to read into that, possibly assuming things about one's personality which might not be the case. She could get veneers I suppose, although they're costly. Maybe she's ok with not having them worked on, and if that's the case I think it's fine. William Eustace is another model who I don't see smiling much either, and I think it's for the same reason: his teeth, like Denisa's, aren't beautiful. But they're both successful models, and I think it's great that people can have a successful modeling career even if their teeth aren't perfect.
However, I would like to know why she seems to be based in Spain now, doing so much runway there as opposed to the larger markets.
And does anyone know of any video where she speaks on camera? For awhile now I've been curious to hear what she sounds like.
