Sure, I can understand that ... I just like to give advice on everything :P

Maybe just a last comment on the last design, pay attention that the model should stay standing from his rest position.
I have the filling that if you build this baby for real, he will just fall ahead because there are to much weight in the front part.

I know it might sounds stupid, but this little details can help to make a model more 'robust' ... whatever if it's for real or not :)

... I hope I don't sound to snoob, I have to fight with my english too so sometimes it's hard to give an advice without sounding
like I know everything, or something like that :)

EDIT

That's said the weight balance is quite good when looking at the highres image, it was less obvious in the thumb image ... so forget
my last comment :)
