Hola Gianco,
No I haven't seen the Taun-taun in person (hardly living in Spain
) but from the pics its easy to see. I come from the modelling and fine-art, and sadly (or luckylly) my eye is over trained to catch this things.
I think GG do care about detail, but they are not realy reference obessive, per examble their Speeder bike is too small (10%) when compared to the biker.
I know there were different proportions on the Taun-Taun, and the stop motion puppet is smaller in proportion than the full size, but being the small the one they used for reference to build the prop, I can't see no reason why they make the GG Taun-Taun so big.
This is my never asked question... if you put your time, money an effort in doing something, why don't you make it perfect?
My two cents
VIKING28- do you have more detail pics of the Taun-Taun... in that case would you mind to pm me?
