The two subs look like the two friends in the movie (and graphic novel) Ghost World, particularly the arty little brunette. I'd like to see more of her in the future, though the blonde screams louder. At times there was a bit too much going on to take in at one time... otherwise fun.
Ms Blue looks great but has a rather limited repertoire of moans and screams... gag her! Also, since you have her head in the stock why not shave her bald and apply the violet wand to her newly naked scalp!
