good job !
I like the atmosphere ; suggesting a scary movie shots coming !
if U could turn the camera a little bit downward to let us see more of the body textures, it may help us get the whole picture of the monster, and not wasting your effort on such great textures.
Besides, if U put more Saliva like fluid, dropping down the Tunnel, and in the mouth of it , with splitting it out towards the camera adding a blurred Scum on the right corner of the picture just like sticking on the lens of the camera, could add more realistic and scary mood.
