Well, the competition is now over and a winner was picked!
If you haven't seen it yet, please check out the "making of" post here.
Congratulations to Kevin, the winner of this model. He was kind enough to send me some pictures of it in it's new home. He has it sitting on his desk at work and it looks like Claptrap has some friends also!
Just for posterity, here's some screenshots of the GSUK competition pages along with some of the comments (it's a bit too small to read because of the way Picasa resizes them, but it's more for me than anything :P). Here's the links to the pages on GSUK if they still exist on their website: Page1 & Page2.
Time for the next project!
