This is a creation by Constraction Deva

Constraction Deva’s “Deleo” looks like a cross between a Xenomorph from Aliens, Marvel’s Venom, and the Demogorgon from Stranger things, though it was only inspired by one of those things. Deleo looks like a living, breathing organism, something I could see as a character (or monster?) in a movie. Given the shape and different geometries of LEGO technic and BIONICLE parts, it’s always impressive to see a fully articulated MOC that looks organic, without a bunch of gaps to break the illusion.

As for constructive criticism, the smaller pair of arms could maybe use a bit more detailing to fit better with the curvature of the larger limbs. Maybe swapping out the larger ball joints and CCBS skeleton arms for mixel joints, technic, and system bricks would allow Deva to keep them skinny but add more detail? I also cant help but think one of those rounded curved plates with studs on top would fit perfectly into the pair of flat 1×2 bricks between Deleo’s upper and lower limbs, contributing to his organic design.

You can see more of Constraction Deva’s work on youtube, although there’s not much there and it’s been a while since they last uploaded a video. His Instagram and Flickr are updated regularly though, and the creations posted there are exceptionally good. His other MOCs have a style I would describe as “rounded, organic, and smooth” for lack of better words.
