The blonde thing threw me off for a bit, but she looks awesome as PG. Looks like you had to expand the trademark boob window some for Penny, and she could probably take out bad guys with a flick of her big bushy tail. Nice work.
She actually looks really good as a blonde (especially for me cuz i have a thing for blonde girls ) plus she cosplaying as power girl who is my favorite DC herione, so that makes a nice combo for me XDDDD. Great artwork as always! ^_^
