i love to see concept art...

like little blueprints to big robot arms...that build slightly smaller arms that draw the blueprints used to create even larger mechanical arms that go on to build other arms in some sort of never ending arms race.

good job bro. :3

Hmm, interesting. It's neat to see some of your design considerations.

Yeah, I didn't want the raptors to be the only ones with digitigrade feet, since all of the other characters had the more human-like flat feet. But then I didn't like anybody else's concept because they gave them generic three-toed claw feet with the one large claw, and that kinda makes it less effective as a weapon due to the lack of flexibility. I went with a design that is flexible and doesn't render the claw moot.

Besides, what is a Raptor without its trademark claw?
