This is beautiful and artistic idea, and I like it very much. Your font choice isn't my taste but I think that is your way to say something and that's positive.
I think that background image should be fixed in all browsers but otherwise everything is great. Very franch... :)
I like the aesthetic of the site. Some nitpicky things (not a fan of the font either), but overall it's a pleasant look and feel.
My largest concern (other than the page load time - either your image files are HUGE, or your server is very slow) is jumping from one section to the other is a bit unsettling. The homepage, mots, petite bio and contact all have the same navigation and content area which I like. The other sections move the content area over to the left, the background images change and it's a bit jarring. I would suggest sticking with the same look and feel of the homepage on every subsequent page, or at the very least keep the content area static.
I'd also like to add that you could consider a sharper image for the homepage and mots section. Combined with the light color and hard to read font of the menu it gave me a sense of excessive blur. I don't think if it's the case with others but in terms of usability that blur distracts me, alsmost makes me change the page quicker. - i love the photo composition though.
Overall, I agree that it's a website well balanced with its theme, but after the feedback here, please consider some other menu font.
OMG. What have you done? I Think the menu is awesome, however it does not suit your design in any way. I didn't like the font of the last one, but I don't think this one belongs to the present design. Just taking a look at all the sharp edges and rectangular form of context makes it inapropriate for a rounded-edges menu.
I'm sorry if I am harsh, but it is my sincere opinion.
