it would be cool if you made a vehicle that the AW sat on top of, put its legs inside of it and then controlled the steering by the rotation of its waist if it has one. its legs could control a weapons system & excelerator/movement. just an idea if u still want to make a vehicle
Wahaha! Just need some more brainstorming and sketching I guess. Personally I'm used to sketching a bunch of shapes with Pen and paper.
Should check out videos by Richard Doble from Gnomon Workshop Creature Designer. He can take 1 shape expand it into 4 then 12+ different variations exploring all different possibilities before doing the final render.
