I love the Avventura & Racconto eds (especially the latter - very dynamic!)
As for Rachel's cover - I liked it a ton! Sure, it has a candid quality - but so do many professional photographs nowadays. I think the pink really pops, and I also like the slanted alignment of the text. (The only complaint is that patch of light gray).
Also, as for the complaints about her nose... I seriously don't see anything wrong with it. o_O
