A while ago I brought my digicam to the local industrial area and photographed some cool yellow machinery and stuff. I've always like yellow pneumatic macinery and orange-yellow and black are my favourite colors too. I'm sure we can all agree on the leetness of the cargobay 'lifter suit' in Aliens, but how cool wouldn't it be with a walking tank looking like that?
There's a problem though, in order for such a construction to work there must be a lot of pneumatics placed correctly and that would probably clutter the design (functionality versus looks). This is the reason why I've only used pneumatic arms where they look good.
Anyhow, here are some in progress images. I'll probably won't go any further than this. Finished images seems like 'overkill' to me and a sketch almost contain as much information (at a glance). If I had to model every knob and texture this it would probably take a month.
Initial thumbnail sketches. Yes I know they are crappy, but I put priority in just getting it down on paper. The pilot hatch in in the torso.
Bottom: A gorilla version with a cannon, and a humanoid with long arms (note that the pneumatic 'head' can slide in the arm and thus improve strength.)
Worldcraft boxmodel... I can't model, cuz the tools are all 'mystery meat' in gmax.
