Alright, i dont know if this thing fits into vehicle category or not, but it seems deviantart doesnt have "automated mechanized object" category, so i'll just put it here. This mech is a composite of Spider, Scorpion, Turtle, and Eagle. The head is eagle (although it looked like an alien, but my original concept is an eagle), the body is turtle (spiked one, yeah!), tail and hand are scorpion (the hand was converted into a weapon pylon), and the legs are spider. This is my work from 2 years ago, now I re-render this thing with new rendering system.
