Well, most Toa are about the same size, yet the Mata are tiny compared to the Inika.
Also, you probably could have at least made the pins on each leg symmetrical.
Edit: Finally got around to taking apart my MOCs. I should have something by tonight.
Edit 2: Done.

I've been waiting years to use that claw, and I think it worked pretty well on this MOC. So yeah. It can open and close, too. The buzzsaw was kinda improvised, as was the head. I couldn't find a Skakdi head at the last second, so I had to use a Metru head. I guess it works, since it was supposed to be deformed, and a Metru head kinda looks like a gray, shriveled Piraka skull anyway. Legs are digitigrade for no reason besides that regular plantigrade legs are boring.
Also, TENTACLES! And they have pretty good articulation, too.
More pics available at request and stuff.
