In The Thick

To follow up on previous comments the creature anatomy is weird. It goes head, torso, two arms, and barbed tail (no legs). That's what I've gleaned from the trailer and bits of concept art from the far reaches of the interwebs, but it looks like you got it right anyway. As far as your piece goes I think your foreground is interesting (second monster from the right is best due to being the full creature), but your background is really lacking. I know its supposed to be a silhouette, but the contrast in detail between fore and background is really distracting. Since there's so much time left I think it would be worth working on a little more.
