I like your creation of all that beautiful, empty white space Gaelle!It really makes the periwinkle blue color you used for your title and edging really stand out!
I'm not exactly sure what's happening in the photo, but I do like the shades of blue and teal as well as the pretty patterns. I also like the blue-and-white cord on the right side and bottom of your layout, and the same blue on the delightful font you used for your title.
