There is a double negative in the last panel "I can't never tell..", but I say you keep it in and turn her into a recuring hillbilly character a-la Deliverance.
d'oh. I rewrote that line so many times with 1 negative each that the final ended with a double negative. Most times if I made a mistake like that, I'd leave it and turn her into a hillbilly character. But I already have my next few written. Thanks for the catch. I'm going to fix it.
Art Tip: The skew tool in photoshop really helps fixing things when drawing in perspective.
