No worries.
On a negative note, that page you link to must be quite old - most of the links are dead.
I'd be careful as well - the C-3P0 model looks like it belongs to a chap I know on a card modelling forum, and he is VERY shirty with sites that steal his stuff and don't credit him. The site that it links to is not his site. He has locked away and protected his models as a result of people crediting themselves as the creators of his models. He is an AWESOME designer, though. He's just finished a cutaway X-Wing that is nothing short of spectacular...
I'm not allowed to reveal his website address.
If you want awesome card models, check out
papermodelers.com and
zealot.com (I'm a member of the latter).
Be careful on Zealot, because they have a strict code of conduct there (due to a LOOOONG history of people really taking the mick), but they are a great group of guys.
