-Love the post-card idea, with the photos. It's very nice, and a great way to make me think of vacations at the beach.

-Usually I don't like it when stuff is super faded, but the way you did it makes the sig seem very dream-like, which fits your spring theme well.

-Gah, I give up already. It's a masterpiece, what can I say? Quite possibly the best out of all the entries this month. It's small, but it packs a punch.
