I finally registered so I can post in this thread.
I did several of these a while ago:
Sauron Kirby:
Raziel Kirby: (from Legacy of Kain: Soul Reaver and its sequels)
And GLaDos Kirby:
I hope DeviantArt hotlinks work....
I posted the lower-res images since the full views are a little large- but if anyone wants them, they're up on my DeviantArt page (Kirbies gallery: http://shrakner.deviantart.com/gallery/#Kirbies)
