I'm all for waiting until the end to get your relievers, but you don't appear to have a single expected closer. Which is fine, as long as you intended to do so.
Offense looks good overall. I have questions about a couple of the back-end bench players you picked up (Vlad, Davis, Barmes, and Matsui all scare me too much to even think about them, even at just a buck), but nothing that can't be explained by "we all have our gut feelings". I suspect you overpaid for Harper (Unless its a keeper league, in which case you probably have a bargain). I'm in the same boat as you (auction newbie this year).
Pitching seems uneven, perhaps a little thin.
