Of course this doesn't hold true for the numerous guest artist strips included in the series, but Alexiuss works with actual models when he does strips. It's the interesting art style that's generated by this practice that drew me into the comic to begin with.
cycling through 53 of them, 30 seconds each, so every time I look I'm greeted with a new awesome RA scene. Discovering the slideshow option is the most wonderful thing that has happened to my desktop ever.
