...couple of aliens, that is! har har The first one is a rather blatant derivation of one of the Locust Grubs. What can I say? I've been playing a lot of Gears of War for the PC lately. I mainly wanted to give these guys a sense of weight and mass, like the rather heavyset Boomers.
The second is an insectoid alien with tribal trappings. I really wanted to give these guys a distinctive gait due to their toothpick, flamingo-esque legs. I imagine they move in a strange, ostrich-like fashion. Their clothes and weapons reveal a primitive, yet unmistakably intelligent lifeform.
