Imma with Cilein, super work.

 Yay!  

Great, adjustments all in the right direction, voted and 5 stars.

 Thanks everybody! I made some changes. I hope they help to illustrate the concept better.

OMG! very cool!

I really like this, great work! :) especially with your dithering

I wholeheartedly agree with Cilein.

Pretty awesome, love the idea and the lighting and coloring works a treat for giving it a strong impression. The head especially however makes it look more like a slime monster has landed on top of a robot and is coating the metal with its body. If you want to make it like the creature lives within a robotic shell I'd suggest making the joints between 'bones' be made the red slime, in addition to the oozing you have at some. The 'head' of your creature looks like a hoody for the robot. This is my favorite piece put forward yet, the eye, the red tones, the outlines dithering and the overall shapes involved are brilliant <3
