Romantic Blue Cake with White Chocolate Roses

Another cake order for my best customer!  This one was for her mother's birthday.  She said to do whatever I wanted and to make it really pretty.  Fun for me!  This is vanilla cake with raspberry filling and vanilla buttercream.  The roses are my first attempt at working with rolled chocolate (white chocolate in this case).  It worked out pretty well - I've made enough flowers out of play-doh in my life to have a little bit of an idea of what to do.  Although the flowers are chocolate, I don't know if it's something that anyone would really want to take a big bite of...  What do you think?
