Could use a fresh eye

[Wardy]

Really liking it, very creepy concept, my only advice would be to try to make the red lines complement the form of the people. For example, the bit coming past the skull could curve with the mans back before fading. Also, perhaps have the woman leaning back a bit more, so you get the feeling of collapse, or have her back leg obviously dragging to show that she is limp.
Just a few pointers, good luck with it :)
