The looks of this kinda reminds me of a creature in a book I read a long time ago. The Edge Chronicles, I think it was. There was something called the Rotsucker that turned its prey into a liquid with some sort or acidic saliva, I think, and it would then slurp up the liquid in order to feed.
Rambling aside, this is really fantastic. A perfect Halloween monster, if you don't mind me saying. Excellent work here. Praise to you.
Your description rustled my jimmies a little, I was eating... The creature looks amazing! The shading and lighting are great! I would love to have one of those as my pet, if not for that nasty tendency of transmitting deadly infections thingy.
