It looks fucking sexy !
I was thinking you should add a "scale element", like a person standing in front of it. Something like a human would measure 1/4 or 1/5 of the height of the robot-plant.
Since it's a badass carnivorous plant, people should be small enough to be eaten through the top of its head
Also thinking the head should get some more flower-ish features like a pistil and bright colors, bringing it closer from a flower than a green plant ^^ some curvy "tongues" to digest its prey !
I like willy's suggestion to add robotic wires rooted to the ground !
The whole thing is looking pretty awesome already tho.
