I think it's an strong start with a nice introduction of a few of the supporting cast. I liked that Karen has a male assistant. I do think Power Girl should display a little more of her abrasive side so she's not just your typical nice superhero. Ultra-Humanite is a good villain for her, but I hope Palmiotti and Gray will give her her own arch-nemesis, someone who is a physical match against a Kryptonian. They should also emphasize the Power part of her name so that a female hero can get in on some of the spectacular feats male heroes get all the time. Amanda Connor's work is now at her peak, and I'm liking it a lot more than I was expecting. Previously I had found her art a tad too cartoony.
