The torso build is unique and created by me, at least, I never seen other MOCs do something simmilar, If you did then let me know in the comments!
The piculiar thing about this build is that studio shows it as impossible with 4 axle connectors, but building it in physical is perfectly possible, I recommend using a leg double-socket with poor friction, so it wouldn’t be a big deal to put the stress on as the building technique is illegal.
This is a gorgeous build. Love the new claws, the new torso, the way the Vahi attaches to the head.
The only thing that is off is the Piraka armor on the shoulder seems to be a different shade of gold than the rest, could be the render settings but it looks brighter. So does the hordika foot but I know you wanted it to only use parts that exist though so it can actually be built so it’s all good
From dream-builders/masters of disaister sets, I’d say it’s the best piece you can get from them, it’s fairly sturdy and compatable with standart pins.
