Hehe cool images. Unfortunately we can only used images approved by Nick Park. He reviews them on a fairly regular basis and ones that look too old or aren't in-keeping with the current Wallace & Gromit design are removed from the list.
I can imagine when you have been working with characters for so long you become quite a perfectionist. I bet it's the same for a lot of you guys - you look back at models/animations you made 2-3 years ago and you don't think they are as good as your current work....
PS kieran - I read all your messages so you don't have to address them all to Aardman. Perhaps try to shorten the titles a little bit as well if you can?
