hmmm... interesting, and menacing at the same time.
i love how you did small details like shrickta's left arm (the severed one) being less muscular than her right arm, due to the lack of excersize (due to the lack of lower arm), pretty clever, and i liked how you showed her insane smile despie her wisdom(if i am correct and she is wise)

also, krazik seems pretty strong and confident about this, considering how calm she is for a student that is pinned down by their teacher.
also she has a great set of boo- i mean eyes. yes!

do more of them, this seems like an interesting story, waiting to be unfolded.
