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 :)

no carry on giving comments mate, its left to the user if he or she takes it onboard :)
yes i know the weight thing and i always try to model as it would be in the real world as that is what my clients pay me to do:). although sometimes its nice to do something that is just foolish in a technical manner but nice to look at. god knows ive done a few of those. i shall attempt to make a start on the mech 1 concept as i feel it is better, but though i would practise on his poor little weaker brother first :)
so keep replying and keep watching mate
