Just finished The Pyro, based on this concept by Buckster. I'd love to model all of his Team Fortress 2 redesigns, so this is probably the start of a larger project.
Quite happy with how it turned out.
Here's a small sample of the characters I did for Sacred Citadel. These are the characters that have been revealed and can be seen in the Sacred Citadel trailer. More to come when the game is released.
