Kiveun, thanks, I've been keeping an eye on your entry as well, and the model is looking great so far

UPDATES:

Last night (friday): I was pretty spent, so I decided to watch a movie (Der Untergang/Downfall - amazing movie), and didn't get much modelling done.

Today: First update (hopefully there'll be at least one more), been playing around with the idea of giving him one mechanical arm that his claws can retract into. Still more detail to come, and the organic arm is still underneath, so don't mind the few places where it sticks out...
