Reading this now, I can admit I used to go too far with Roxy's accent. Little hints of the way a character speaks works better in type for me than attempting to spell it all out. Roxy should sound Southern (US), but in panel 2 you can almost smell crystal meth coming off the page! (As a resident of Florida, I can make that joke.)

The art here is unfinished, and I am unhappy with most of it... But I gave Roxy pretty eyes in panels 2 and 3, and that is worth mentioning.
