Really good concept and nice image! Well done! 
Thatās some nice work! 
Thatās insane! Tentacles could be improved but overall its a one of a kind piece. Looks like it could be featured in Scott Westerfieldās āLeviathanā
incredible work!! I am so envious
The mouth is the large opening on his head which looks like a mouth. It has teeth and jaws.
The head is located slightly to the right and up from the centre of the image. Look for an object that looks like a head.
From then on, you should be able to locate its mouth. If not, see some reference imagery on the net on what a head (any head will do) looks like.
Awesome. Even made it my desktop wallpaper.
No truer words have been written in this thread.
Great work. I do agree, however, that the tentacles do need a bit of water tossed on them. 
Absolutely excellent! Would love to see an animation of it in action. I can only imagine what it eats.
Excellent design and nice idea too!
It looks good. A work of art.
Very nice robot. A bit scary, but very nice indeed.
This is a great scene. The tentacles remind me of Serge Birault, but then again itās difficult not to think of his work when I see tentacles 
Great model!
Amazing job! To me the look of the tentacles donāt look quite right, but still an amazing piece of work!
Well Done! It looks great.
